68282f55b8 arm: Remove unused ST-Ericsson u8500 arch
This arch does not seem to be supported / used at all in the current
U-Boot mainline source tree any more. So lets remove the core u8500 code
and code that was only referenced by this platform.

Please note that this patch also removes these config options:

- CONFIG_PL011_SERIAL_RLCR
- CONFIG_PL011_SERIAL_FLUSH_ON_INIT

As they only seem to be referenced by u8500 based boards. Without any
such board in the current code, these config option don't make sense
any more. Lets remove them as well.

If someone still wants to use this platform, then please send patches
to re-enable support by adding at least one board that references this
code.

62c390f8a3 mtd: nand: fsmc: Fixes and cleanup for fsmc_nand_switch_ecc()
This patch addresses some comments raised by Scott in the last versions.
Here the changes in detail:

- Removed __maybe_unused as its not needed
- Added check for strength == 4 and error out for the unsupported
  ECC strength values
- Don't set .caclulate, .correct, and .bytes for NAND_ECC_SOFT_BCH as this
  will be done in nand_scan_tail()
- Set .caclulate back to fsmc_read_hwecc() in the HW case
- Added comment that this function will only be called on SPEAr platforms,
  not supporting the BCH8 HW ECC (FSMC_VER8)

817e48d8a2 env: import: hashtable: Prevent buffer overrun when importing environment from file
Lets consider following scenario:
- One uses echo -n "key=value" to define environment variable in a file (single variable)
- The file content is "key=value" without any terminating byte (e.g. 0x0a or
0x0d).
- The file is loaded to u-boot non zero'ed RAM buffer (with load command).
- Then "env import -t -r $loadaddr $filesize" is executed.
- Due to lack of proper termination byte we have classical example of buffer
  overrun.

This patch prevents from this by allocating one extra byte than size and
explicitly null terminate it.

There should be no change for normal env import operation after applying
this patch.

d9cbb264e8 imx: mx6ul: support mx6ul 9x9 evk board
This patch is to support mx6ul_9x9_evk board based on mx6ul_14x14_evk,
the difference between mx6ul 9x9 evk and mx6ul 14x14 evk are:
1. mx6ul 9x9 evk use pfuze3000, while mx6ul 14x14 evk use DCDC.
2. mx6ul 9x9 evk supports 256MB LPDDR2, while mx6ul 14x14 evk
   supports 512MB DDR3
3. mx6ul_9x9_evk use 9x9 package, while mx6ul_14x14_evk use 14x14 package.

This patch add the following:
1. Discard PHYS_SDRAM_SIZE from header file, use imx_ddr_size()
2. Introduce a macro is_mx6ul_9x9_evk using
   CONFIG_IS_ENABLED(TARGET_MX6UL_9X9_EVK) to avoid "#ifdef xxx" in non-SPL
   part. To SPL part, CONFIG_IS_ENABLED(TARGET_MX6UL_9X9_EVK) can not work,
   so still use "#ifdef CONFIG_TARGET_MX6UL_9X9_EVK" to differentiate with
   mx6ul_14x14_evk. And we have no way to dymaically checking this chip
   is 9x9 or 14x14.
3. mx6ul_9x9_evk use pfuze3000, so enabled POWER related configurations.
   POWER related configurations also effect for mx6ul_14x14_evk. But
   power_init_board implementation using 'if (is_mx6ul_9x9_evk())' to
   do initialization for mx6ul_9x9_evk, and do nothing for mx6ul_14x14_evk.
4. mx6ul_9x9_evk use lpddr2 with size 256MB, so add related SPL DRAM
   configurations.
5. Enable CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG and setting dtb file
   according to board_rev and board_name.
6. Add TARGET_MX6UL_9X9_EVK Kconfig entry

7bebc4b04e imx: imx7d: clock control module support
* Add Clock control module (CCM) support
* iMX7D SoC introduces 3 main clock sysmtem abstraction for clock
  root frequency generation denominated clock slices.
  Core clock slice: hihg speed clock for ARM core
  Bus clock slice: for bus clocks
  IP clock slice: Peripheral clocks
* At system boot ROM enables PLL_ARM, PLL_DDR, PLL_SYS, PLL_ENET
  In u-boot, we have to:
  - Configure PFD3- PFD7 for freq we needed in u-boot
  - Set clock root for peripherals (ip channel)
