We used to collect all sections beginning with __clk_of_table_ in a single
section in the linker using KEEP(*(.__clk_of_table_*)). That the sentinel
entry ended up as the last entry was pure luck, but not always the case.
Instead of putting all entries in different sections we now put all entries
in the same section. Only the sentinel entry gets its own section and is
collected by the linker separately.

USB requests should be processed within a timeframe of 5s.
The linux kernel also uses this timeout value for the control packets.
For the musb the increase in timeout helps successfully probing USB devices
(at least on one test hardware), but on the other hand doesn't slow down the
system, if there are no devices, i.e. the timeout never hits. That means,
that the USB core correctly aborts instead of timing out.
Why and how the 100ms was chosen in the first place, can not be deduced from
the git history, just that it seems to work fine for most boards.
Change USB_CNTL_TIMEOUT to 5000ms and replace all occurences of
`USB_CNTL_TIMEOUT * x`
with just
`USB_CNTL_TIMEOUT`,
as the timeout is now large enough without it.

Since 2011 barebox' of_device_id struct uses unsigned long type for data field:
struct of_device_id {
char *compatible;
unsigned long data;
};
Almost always struct of_device_id.data field are used as pointer
and need 'unsigned long' casting.
E.g. see 'git grep -A 4 of_device_id drivers/' output:
drivers/ata/sata-imx.c:static __maybe_unused struct of_device_id imx_sata_dt_ids[] = {
drivers/ata/sata-imx.c- {
drivers/ata/sata-imx.c- .compatible = "fsl,imx6q-ahci",
drivers/ata/sata-imx.c- .data = (unsigned long)&data_imx6,
drivers/ata/sata-imx.c- }, {
Here is of_device_id struct in linux kernel v4.0:
struct of_device_id {
char name[32];
char type[32];
char compatible[128];
const void *data;
};
Changing of_device_id.data type to 'const void *data' will increase
barebox' linux kernel compatibility and decrease number of 'unsigned
long' casts.
Part of the patch was done using the 'coccinelle' tool with the
following semantic patch:

This adds simple console support to the PBL which makes it
possible to print more complex messages in the PBL than just
strings or hex numbers. For now puts_ll is used to print the
messages, so it depends on CONFIG_DEBUG_LL which makes it
more a debugging option. However, this could be extended later
to get regular output from the PBL if desired.

This commit adds support for Marvell's 88E1543 PHY chip. This chip is
almost identical to the 88EE1545, except the 88E1545 supports QSGMII
and the 88EE1543 supports SGMII.
Therefore, the same configuration function is used for both PHYs. For now,
the only initialization provided for the 88EE1543 is the LED setup.

This could previously only be done with 'devinfo global'. While
this is still possible this adds a more direct access via the
globalvar command. This variant also adds a '*' in front of
the variable if the corresponding non volatile variable exists.

This adds (back) support for non volatile variables. Non volatile
variables are variables which are stored in the environment over
reboot. They are used in the same way as the global variables, but
with a 'nv' command and device. The variables are stored under
/env/nv/, one variable per file. Adding a nv variable automatically
adds a global variable with the same name. Changing a nv variable
also changes the same global variable, but not the other way round.
This allows for example to configure the username as:
nv user=sha; saveenv

Sometimes mbr is erroneously recocognised as FAT partion. Due to this the mbr
partition parser is not being called and the partitions on the media are not
detected. This patch should fix the problem. The checking is done as in the
linux kernel.
I have seen the problem using usb sticks. Although partitioning and formatting
them under linux. The file system type field in the mbr remains there which
causes the wrong detections as FAT32 type and not as mbr.
