We currently have to special case blspec entries vs. boot scripts
in the common boot code since we want to print different informations
about them. This adds a 'title' and 'description' which can be filled
in with different information by bootscripts and blspec entries and
so we get rid of the special handling.
Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
The code in common/boot.c collects the different boot entries in
lists of type struct blspec, eventhough many of them may not be
bootloader spec entries but for example boot scripts. This is the first
step of separating the data structures from boot entries and bootloader
spec: As struct blspec is merely a container for collecting boot entries
We simply rename struct blspec to struct bootentries. No functional change.

With this patch nv variables are automatically saved whenever barebox
shuts down (that is 'reset' is executed or a kernel is started). With
this the additional 'saveenv' step becomes unnecessary.
The nv variables are stored in the environment and the estasblished
behaviour is that files in the environment must be manually saved
using 'saveenv'. This behaviour shall be kept for now, so this patch
cannot just call 'saveenv' since that would save the modified
environment files aswell. Instead we read the environment from the
device, modifiy the nv variables and save the environment back.
Since this changes a long existing behaviour messages are printed the
first time a nv variable is modified and during shutdown when the
variables are actually saved.

The state framework grew organically over the time. Unfortunately the
architecture and abstractions disappeared during this period.
This patch refactors the framework to recreate the abstractions. The
main focus was the backend with its storage. The main use-case was to
offer better NAND support with less erase cycles and interchangeable
data formats (dtb,raw).
The general architecture now has a backend which consists of a data
format and storage. The storage consists of multiple storage buckets
each holding exactly one copy of the state data. A data format describes
a data serialization for the state framework. This can be either dtb or
raw. A storage bucket is a storage location which is used to store any
data. There is a (new) circular type which writes changes behind the
last written data and therefore reduces the number of erases. The other
type is a direct bucket which writes directly to a storage offset for
all non-erase storage.
Furthermore this patch splits up all classes into different files in a
subdirectory.
This is currently all in one patch as I can't see a good way to split
the changes up without having a non-working state framework in between.
The following diagram shows the new architecture roughly:
.----------.

Non volatile device variables are used to make device parameters
persistent. They are like normal non volatile variables, but set
the values of the device parameters with the corresponding name.
Every nv variable beginning with nv.dev is a non volatile device
variable. They have the form nv.dev.<devname>.<paramname> and act
on the parameter <paramname> of the device named <devname>.
The non volatile device variables are designated for example for
video modes, ethernet device ip addresses or mtd partitioning.

fixes: 81737c1 mtd: Fix erasing of devices >4GiB
Several places erased a complete flash partition passing ~0 as count to
erase(). With the above commit count to erase was changed from an unsigned
type to a signed type, so the (count > f->size - offset) check in
erase() no longer triggers and the ~0 count is no longer adjusted to the whole
device size. Among other things this results in saveenv failures on NOR
flashes.

whole device which is tested for in erase(). All other negative values

This patch makes the update to Nand robust against power
failures. With this we make sure that during every step of the
update at least one of the two images on Nand is readable and
valid.
Also this patch makes it possible to refresh/repair the boot
images on Nand. This may become necessary when a previous update
has been interrupted due to a power cut, or when the number of
bitflips is near to the number we can correct. This is also done
in a way that allow power cuts at every step.
We assume the following layout in the Nand flash:
fwmaxsize = (n_blocks - 4) / 2
block
0 ----------------------
| FCB/DBBT 0 |
1 ----------------------
| FCB/DBBT 1 |
2 ----------------------
| FCB/DBBT 2 |
3 ----------------------
| FCB/DBBT 3 |
4 ----------------------
| Firmware slot 0 |
4 + fwmaxsize ----------------------
| Firmware slot 1 |
----------------------
When the layout found on the device differs from the above the update
won't be robust, but nevertheless works. Since the layout is changed
to the above during the update, the next update will be robust.
Here's the strategy we use to implement a robust update:
The FCBs contain pointers to the firmware slots in the
Firmware1_startingPage and Firmware2_startingPage fields. Note that
Firmware1_startingPage doesn't necessarily point to slot 0. We
exchange the pointers during update to atomically switch between the
old and the new firmware.
- We read the first valid FCB and the firmware slots.
- We check which firmware slot is currently used by the ROM:
- if no FCB is found or its layout differs from the above layout,
continue without robust update
- if only one firmware slot is readable, the ROM uses it
- if both slots are readable, the ROM will use slot 0
- Step 1: erase/update the slot currently unused by the ROM
- Step 2: Update FCBs/DBBTs, thereby letting Firmware1_startingPage
point to the slot we just updated. From this moment
on the new firmware will be used and running a
refresh/repair after a power failure after this
step will complete the update.
- Step 3: erase/update the other firmwre slot
- Step 4: Eventually write FCBs/DBBTs again. This may become
necessary when step 3 revealed new bad blocks.
Refreshing the firmware which is needed when when blocks
become unreadable due to read disturbance works the same way,
only that the new firmware is the same as the old firmware
and that it will only be written when reading from the device
returns -EUCLEAN indicating that a block needs to be
rewritten.

unsigned images. Since currently FIT is the only image type which
supports signing, this means with this option we enforce using FIT
images. All additionally passed in device trees and initrds will be
ignored, so that only the ones from the FIT image can be used.

This implementation is inspired by U-Boot's FIT support. Instead of
using libfdt (which does not exist in barebox), configuration signatures
are verified by using a simplified DT parser based on barebox's own
code.
Currently, only signed configurations with hashed images are supported,
as the other variants are less useful for verified boot. Compatible FIT
images can be created using U-Boot's mkimage tool.

So long struct bootm_data.verify is a bool which enables CRC checking
(hashing). Extend this to a enum and add support for signature checking
in the same option. This also adds the corresponding globalvar and a
-s option to bootm.

The uImage format uses numbers for to identify the different
parts of a image, but the FIT image format uses names. To better
integrate the FIT image format into bootm always use names and
convert them to numbers when necessary.

This adds the ability to control barebox over serial lines. The regular
console is designed for human input and is unsuitable for controlling
barebox from scripts since characters can be lost on both ends, the data
stream contains escape sequences and the prompt cannot be easily matched
upon.
This approach is based on the RATP protocol. RATP packages start with a
binary 0x01 which does not occur in normal console data. Whenever a
0x01 character is detected in the console barebox goes into RATP mode.
The RATP packets contain a simple structure with a command/respone
type and data for that type. Currently defined types are:
BB_RATP_TYPE_COMMAND (host->barebox):
Execute a command in the shell
BB_RATP_TYPE_COMMAND_RETURN (barebox->host)
Sends return value of the command back to the host, also means
barebox is ready for the next command
BB_RATP_TYPE_CONSOLEMSG (barebox->host)
Console message from barebox
Planned but not yet implemented are:
BB_RATP_TYPE_PING (host->barebox)
BB_RATP_TYPE_PONG (barebox->host)
For testing purposes
BB_RATP_TYPE_GETENV (host->barebox)
BB_RATP_TYPE_GETENV_RETURN (barebox->host)
Get values of environment variables

The async poller does not work as expected since it can happen that
the async poller is removed from the list of pollers while we are
iterating over the list. Even list_for_each_entry_safe does not help
here since we may remove the next list element, but
list_for_each_entry_safe only allows to remove the current list element.
Rework the async poller so that it is registered with the poller
framework on registration and then is only marked as active with
poller_call_async(). This way we do not have to do list manipulations
while running the pollers.

Currently it is not possible to change symbolic links in the default
environment. For example if the default environment contains the
link "current_boot -> mmc" then the following does not work:
$ rm current_boot
$ ln net current_boot
$ saveenv
After reset the link is still pointing to "mmc" and this error appears:
"symlink: /env/boot/current_boot -> net : error -17"
The patch fixes the above problem and moves the "ENV_FLAG_NO_OVERWRITE"
to enable handling of symbolic links in this case too.

pstore is a persistent storage filesystem used for RAMOOPS. It is used
to store console logs, panics, ftrace and other information in case of a
crash/panic/oops/reboot.
pstore is implemented for barebox as a read-only filesystem at the
moment. It may be extended later on. The idea is to provide a way to
extract essential data from the last running kernel.
Most of the code is copied from the kernel. However this is only a
lightweight implementation without real write support yet.

In commit 104a6a7ccf support was added
for Thumb2. It added do_execute() as a way to provide arch dependent
calling veneers for use in "go" and thumb2_execute() as the thumb2 to
arm veneer.
But thumb2_execute() isn't necessary as gcc generates a proper calling
sequence from a standard function pointer call. Thumb2 barebox is
compiled with the AAPCS ABI which requires this.
It also had a bug and didn't pass the arguments properly, but code
execute via "go" rarely uses arguments so this wasn't very noticeable.
Since thumb2 was always the only user of do_execute(), go ahead and
delete that too.

While this simplifies the code as is I got the request to continue on
errors in memtest, which can be better implemented when the messages are
printed inline and not at the end of the function.
This reverts commit 4ff9e28abc.
unprotect(), erase() and protect() return EOPNOTSUPP errno code
for at24 I2C eeproms, so envfs_save() doesn't store data
to these eeproms without this patch.
