cda8f87349 caam: Fix crash in case caam_jr_probe failed
If probing caam_jr returns failure, the variable "dev" will not be
initialized, so we can't use dev->name for the error print.
Otherwise it will cause crash.

b9d66a061b imx: Convert SERIAL_TAG support to ENV_VARS_UBOOT_RUNTIME_CONFIG
No iMX platforms have supported ATAG-based booting.  They have however
re-used the CONFIG_SERIAL_TAG option as a way to enable support of
reading the OTP fuses and setting the serial# environment variable in
some cases.  Change the warp7 support to use this symbol, use this for
updating the rest of the imx7 code, and update the imx8 conditionals.

401d1c4f5d common: Drop asm/global_data.h from common header
Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

6aead23323 imx: imx8qm/qxp: Recover SPL data section for partition reboot
When doing partition reboot, the boot image won't be reloaded by ROM,
it is just CPU reset to boot entry. The SW has to keep the boot image
inside the RAM unchanged. It includes both the TEXT section and DATA
section.

For SPL, the problem is DATA section will be updated at runtime, so in
next partition reboot the data is not same as the initial value from
cold boot. If any code depends on the initial value, then it will have
problem.

This patch introduces a mechanism to recover the data section
for partition reboot. It adds a new section in image for saving
data section. When from cold boot, the data section will be saved
to that new section at SPL early phase. When from partition reboot,
the data section will be restored from the new section.

7c351ff5e0 imx: imx8qm/qxp: Fix issue in get_effective_memsize
When Trusty OS allocates the mem region from 0xfe0000000-0xffffffff,
the get_effective_memsize does not return correct memory size.
There is a check in get_effective_memsize to find the memreg where
the u-boot is running, and return the size of that memreg as the result
of get_effective_memsize. When using aligned start, the value is
0x80200000 since it is 2MB aligned. Thus the finding of memreg will
fail and return the PHYS_SDRAM_1_SIZE because u-boot text base is
0x80020000. This cause u-boot is relocated to the high memory where has
been occupied by Trusty OS.

6fcb2ee783 imx8: Replace SC_R_LAST with SC_R_NONE in DTB
We are currently using SC_R_LAST as a marker for imx8 power domain tree
nodes without a resource attached. This value is compiled into dtb as
part of the linux build and used by uboot.

The SC_R_LAST constant changes frequently as SCFW resources are added
(by design) and every time we need to update linux and uboot headers
together or boot can fail.

Fix this by replacing SC_R_LAST usage with a new constant SC_R_NONE
defined to be 0xFFF0.

9382f73bb0 imx8: cpu: restrict checking ROM passover info for revA
Passover info only for revA.

move get_cpu_rev out of CONFIG_CPU to avoid build failure when using
get_cpu_rev in SPL.
Add a CONFIG_SPL_BUILD for passover usage, no need to execute it again
in normal U-Boot stage. Also if still checking passover info in normal
U-Boot stage, need to make the passover code executed after
arch_cpu_init_dm.
So to make it easy and clean, only execute the code for SPL stage.
