On the Utilite board this delay is necessary to prevent a link timeout.
It seems the values written to GPR13 have to settle for some time before
further accesses may be made.

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 type;
identifier func;

func(...) {

As a lot drivers currently rely on the 1:1 virt->phys mapping on ARM
we define DMA_ADDRESS_BROKEN to mark them. In order to use them on
other architectures with a different mapping they need proper fixing.

Compiling the tree with allyesconfig is helpful because different
compilers (gcc, clang) or static checkers (e.g. clang's scan-build)
can then process and check more code.
This patch introduces two new configuration symbols that Kconfig files
can depend on. That way, code that is only working where a cache or DMA
implementation exists can be opted out.

Embedding struct ata_ioports into struct ide_port saves us an allocation.
Making it available to client drivers is necessary to give them access
to struct ata_port which is needed in the next patch.

ata device usually take a long time to spin up, so it makes sense
to only spend this time when the device is actually used.
This adds a logical ata device and attaches a 'probe' parameter
to it, similar to what MMC does.
