When the last line in a config file has no newline then 'next' is NULL
on the the loop iteration. Check that before derefencing 'next'.

RATP console selects RATP, which in turn selects CRC16, but those
chains don't work in Kconfig, so select CRC16 also from the
console option.
Also fix build errors by depending on CONSOLE_FULL and selecting
POLLER.

Ramoops may be useful even without oftree support, as kernels
booted without a DT may have other means to reserve the
ramoops memory.
Fixes:
In function `ramoops_probe':
undefined reference to `of_add_reserve_entry'

When a device probe fails the device is removed from the active list.
If then the device is unregistered afterwards it is removed from the
active list again resulting in a crash. To fix this initialize the
devices active list entry when removing it from the active list.

Large SPI-NOR (>2MB) chips reuire more than 40 seconds to perform
all-chip erase. This patch adapts
09b6a377687b885565339e60bc62566433a0406f from Linux kernel, which
implements simple heuristics in order to calculate appropriate wait
time (see orignal commit's description for more details of the fix)

Using NFS in conjunction with boot spec and the feature to let Barebox
auto generate a kernel command line must keep the options the NFS filesystem
was mounted in Barebox. This patch extends the kernel command line parameter
on demand if something different than the defaults are used.
The command:
barebox:/ boot nfs://myhost//root
expands to the kernel command line:
nfsroot=myhost:/root,v3,tcp
while the command:
barebox:/ boot nfs://myhost:2049//root
expands now to the kernel command line:
nfsroot=myhost:/root,v3,tcp,mountport=2049,port=2049

Instead of returning an error when a locked region is read, fill
the result with 0xbadabada to indicate a locked region is read.
This way a md -s /dev/imx-ocotp does not abort when it encounters
locked regions.

Throughout our codebase the private context pointer is the first
argument to a function. Do this for the ocotp driver aswell.

Even when the control register has offset 0x0 it's still nice
to use a register define for it. Accessing priv->base directly
just looks wrong.

This adds initial regmap support. Function prototypes are from
the Kernel, the implemention is mostly rewritten. Currently the
regmap support is limited to the bare minimum to get started.

The HABv4 functions need access a part of the ROM which is
located in the zero page. This must be done early, before the
MMU has been configured and the zero page has been set to faulting.
The HAB functions currently use cpu_is_imxxy(). At the stage where
HAB is called the i.MX CPU type variable is not yet initialized,
so this code only works when only one i.MX type is enabled and
cpu_is_imxxy() are compile time constants.
To fix HAB support when more than one i.MX type is enabled make the
HAB status function SoC specific so that we can drop the use of
cpu_is_imxxy().

This shouldn't be necessary. So far it didn't hurt either, but now
this invalidates the signature of the image, so keep the image
unmodified.

When a whole block of 4KiB in an ubifs file is zero then the block is
not stored in the filesystem. read_block() returns -ENOENT in this case,
so this return value must be treated as success.

For USB upload we must execute the DCD table manually and
invalidate the DCD table in the uploaded image afterwards
to prevent the ROM from executing the DCD data again. Doing this
changes the image and thus also invalidates the signature. To
make HAB signed images suitable for USB upload possible we add an
option to create HAB signed images suitable for USB upload. With
this option the image is created like this:
- The image is created like usual, but with already invalidated DCD
data (DCD length is set to zero)
- This image is then signed using the CST
- After this the DCD data is made valid (Set DCD length to the real
length)
imx-usb-loader now finds valid DCD data, executes it and by invalidating
the DCD data it restores the state the image had during signing.

We invalidate the dcd data in the uploaded image since we already
processed it manually. To do so we have set the dcd pointer to 0.
Doing it this way prevents the ROM from executing the HAB code in
debug mode. Use the dcd length instead to invalidate the dcd data.
