1e7a69f661 ARM: imx: hab: panic on authentication failure
Instead of hang()ing the system and thus disallowing any automated
recovery possibility from a HAB authentication failure, panic() .
The panic() function can be configured to hang() the system after
printing an error message, however the default is to reset the
system instead.

This allows redundant boot to work correctly. In case the primary
or secondary image cannot be authenticated, the system reboots and
bootrom can try to start the other one.

b75d8dc564 treewide: convert bd_t to struct bd_info by coccinelle
The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:

  It's a **mistake** to use typedef for structures and pointers.

Besides, using typedef for structures is annoying when you try to make
headers self-contained.

Let's say you have the following function declaration in a header:

  void foo(bd_t *bd);

This is not self-contained since bd_t is not defined.

To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>

  #include <asm/u-boot.h>
  void foo(bd_t *bd);

Then, the include direcective pulls in more bloat needlessly.

If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:

  struct bd_info;
  void foo(struct bd_info *bd);

Right, typedef'ing bd_t is a mistake.

I used coccinelle to generate this commit.

The semantic patch that makes this change is as follows:

  <smpl>
  @@
  typedef bd_t;
  @@
  -bd_t
  +struct bd_info
  </smpl>

3c41728d80 imx8m: Refactor the OPTEE memory removal
Current codes assume the OPTEE address is at the end of first DRAM bank.
Adjust the process to allow OPTEE in the middle of first bank.

When OPTEE memory is removed from first bank, it may split the first bank
to two banks, adjust the MMU table for the split case,
Since the default CONFIG_NR_DRAM_BANKS is 4, it is enough, just enlarge
i.MX8MP evk to default to avoid issue.

2f3c92060d imx8m: workaround ROM serror
ROM SError happens on two cases:

1. ERR050342, on iMX8MQ HDCP enabled parts ROM writes to GPV1 register, but
when ROM patch lock is fused, this write will cause SError.

2. ERR050350, on iMX8MQ/MM/MN, when the field return fuse is burned, HAB
is field return mode, but the last 4K of ROM is still protected and cause
SError.

Since ROM mask SError until ATF unmask it, so then ATF always meets the
exception. This patch works around the issue in SPL by enabling SPL
Exception vectors table and the SError exception, take the exception
to eret immediately to clear the SError.

a1f6d04aa1 ARM: imx: soc: Select default TEXT_BASE for MX7
Select default U-Boot and SPL text base for the MX7 SoC. The U-Boot
text base is picked as the one used by various MX7 boards. The SPL
text base however is different.

The SPL text base is set to 0x912000 instead of the usual 0x911000,
that is because the 0x911000 value cannot work. Using 0x911000 as a
SPL text base will result in the DCD header being placed below the
0x911000 address, which is a reserved SRAM area which must not be
used. This will actually trigger eMMC boot failure on MX7D at least.
Hence the increment.

Update all boards affected by this SPL problem to the new SPL_TEXT_BASE.

3854296801 Revert "imx: rom api: fix image offset computation"
This reverts commit 1f63ee6566.

As reported by Ye Li on ML:

1. Removing the image_offset will break secondary (redundant) boot support for sd and emmc.
2. When booting from emmc boot partition, the image_offset is 0. But the flash.bin
generated by mkimage with imximage-8mp-lpddr4.cfg is for sd. It expects to be burn at 32KB offset.
The fit offset 0x60000 has already included the 32KB offset.  So when you burn this flash.bin
to emmc boot partition at offset 0, the fit offset should subtract the 32KB (0x60000 - 0x8000).

0e06d63d19 ARM: imx: ddr: Add missing PHY reset
The iMX7D RM 9.2.4.9.3 Power removal flow Table 9-11. Re-enabling power
explicitly says both the DDR controller and the PHY must be reset in the
correct sequence. Currently the code only resets the controller. This
leads to a misbehavior where the system brings the DRAM up after reboot,
but the DRAM is unstable. Add the missing reset.

The easiest way to trigger this is by triggering WDT without having the
WDT assert WDOG_B signal, i.e. mw.w 0x30280000 0x25 .

1f63ee6566 imx: rom api: fix image offset computation
When not booting from FlexSPI, the offset computation is:

offset = image_offset + CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR * 512 - 0x8000;

When booting from SD card or eMMC user partition, image_offset is
0x8000. It is useless to add and remove 0x8000.
When booting from other device, image_offset is 0 so this computation is wrong.

Simplfy this computation to work on all booting devices.

0914011310 command: Remove the cmd_tbl_t typedef
We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.

Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.

This requires quite a few header-file additions.

90526e9fba common: Drop net.h from common header
Move this header out of the common header. Network support is used in
quite a few places but it still does not warrant blanket inclusion.

Note that this net.h header itself has quite a lot in it. It could be
split into the driver-mode support, functions, structures, checksumming,
etc.

c3dc39a2f8 arm: Don't include common.h in header files
It is bad practice to include common.h in other header files since it can
bring in any number of superfluous definitions. It implies that some C
files don't include it and thus may be missing CONFIG options that are set
up by that file. The C files should include these themselves.

Update some header files in arch/arm to drop this.

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.
