The code can be used with slight modifications on i.MX28 aswell.
Add a i.MX28 registration function and move the differences to
function callbacks.

We used to use nand0 device for storing barebox and made the assumption
that there is enough space at the beginning of the first device. Instead,
use the barebox partition directly. This requires that the partition
where barebox should be stored is named 'barebox', that is the case for
all boards currently.

When probing from devicetree, the output for several i2c host
controllers prints out a bus number of -1:
i2c-omap 44e0b000.i2c: bus -1 rev0.11 at 400 kHz
i2c-omap 4802a000.i2c: bus -1 rev0.11 at 400 kHz
i2c-omap 4819c000.i2c: bus -1 rev0.11 at 400 kHz
The call to i2c_add_numbered_adapter() in probe finds out the next free
bus number, so we move the output to a location where the number is
already determined.

This adds the missing pieces for:
d8a6e1c ARM/mem: handle data aborts gracefully for md
When possible use memmap and directly and dereference the input pointer
directly in memory_display() so that the data abort occurs where we expect
it and not in the md command. With this d8a6e1c can work as expected.

The CPSW uses DMA, so we should quiesce the device before leaving
barebox. This patch unregisters the CPSW properly on the device
remove callback. To do this we have to fix the error path in
cpsw_slave_setup, since this function can fail and we need a
known slave status in the remove function.

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:
@rule1@
identifier dev;
identifier type;
identifier func;
@@
func(...) {
<...

Commit 6638760c225c37f90e822ebf4dd8f0d2cd0b0ef3
("ARM: mvebu: Enable PUP register")
correctly enables devices that are disabled after boot-up due to
some Design For Testability registers.
However, although harmless on Armada 370, call the code conditionally
on Armada XP only. While at it, move PUP register defines to SYSCTL
registers where they belong to.

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.
