When full malloc is enabled and SYS_MALLOC_F is also enabled, the simple
pre-reloc heap is used before relocation. In this case, calloc() uses
the MALLOC_ZERO macro to zero out the allocated memory. However, since
this macro is specially crafted for the dlmalloc implementation, it
does not always work for simple malloc.
For example, when allocating 16 bytes via simple malloc, only the first
12 bytes get zeroed out. The last 4 bytes will remain untouched.
This is a problem for DM drivers that are allocated before relocation:
memory allocated via 'platdata_auto_alloc_size' might not be set to
zero, resulting in bogus behaviour.
To fix this, use 'memset' instead of 'MALLOC_ZERO' to zero out memory
that compes from simple malloc.

The default implementation of ERR_PTR/PTR_ERR maps errno values at the
and of the address range (e.g. -EINVAL/-22 gets 0xFFFFFFEA).
For socfpga gen5 SPL, this doesn't really work, as the heap is nearly
at the end of the 32 bit address range.
This patch adjusts the ERR_PTR_OFFSET to map errno values into the range
of the Boot ROM, which should not be used for valid pointers.

This patch changes ERR_PTR/PTR_ERR to use CONFIG_ERR_PTR_OFFSET to map
errno values into a pointer region that cannot contain valid pointers.
IS_ERR and IS_ERR_OR_NULL have to be converted to use PTR_ERR, too,
for this to work.

Some U-Boot pointers have redundant information, so we can use a scheme
where we can return either an error code or a pointer with the same
return value. The default implementation just casts the pointer to a
number, however, this may fail on platforms where the end of the address
range is used for valid pointers (e.g. 0xffffff00 is a valid heap pointer
in socfpga SPL). For such platforms, this value provides an upper range
of those error pointer values - up to 'MAX_ERRNO' bytes below this value
must be unused/invalid addresses.

API_dev_write(va_list ap) is currently lacking the write support

This patch was copied from kernel commit: 67fdfda4a99ed.
Sometimes, the gadget driver we want to run has max_speed lower than
what the UDC supports. In such situations, UDC might want to make sure
we don't try to connect on speeds not supported by the gadget
driver because that will just fail.
So here introduce a new optional ->udc_set_speed() method which can be
implemented by interested UDC drivers to achieve this purpose.

imx targets are defined in arch/arm/mach-imx/Makefile.
Some of them are dependent on targets defined in main
Makefile. For the Makefile in arch/arm/mach-imx this
targets must be finished before the imx targets are
build, if not you get for example the error:
make -f /home/hs/abb/mainlining/u-boot/scripts/Makefile.build obj=arch/arm/mach-imx u-boot-dtb.imx
make[2]: *** No rule to make target 'u-boot-fit-dtb.bin', needed by 'u-boot-dtb.imx'. Stop.
make[1]: *** [/home/hs/abb/mainlining/u-boot/Makefile:1123: u-boot-dtb.imx] Error 2
make[1]: *** Waiting for unfinished jobs....
make[1]: Leaving directory '/work/hs/compile/u-boot/aristainetos2_defconfig'
make: *** [Makefile:148: sub-make] Error 2
compile failed
In above case of CONFIG_MULTI_DTB_FIT is defined, the
u-boot-dtb.imx is dependent on the u-boot-fit-dtb.bin
which may is not build yet ...
I could reproduce this error on a travis build also if
I build an out-of-tree build on a local machine with a
build directory on a "slow" slow storage device. If
building the same source target with a build dir on a
fast storage device, the build works.
I found no solution to tell the arch/arm/mach-imx/Makefile
to find the targets in main Makefile, if there is a way
this would be the better fix.
I solved it by adding a IMX_DEPS var, which holds a list
of main u-boot targets, which must be finished, before
calling imx targets and fixed the build for imx
targets which enabled CONFIG_MULTI_DTB_FIT.
I think it is just luck, that imx targets with
CONFIG_OF_SEPARATE enabled build, because the
u-boot-dtb.imx target depends on u-boot-dtb.bin
which gets build early enough before starting with
u-boot-dtb.imx. May this targets should be fixed too.
