RT #87229. LPC43xx/18xx: Fixed clock startup issue (patch by jeff.simpson@allen-heath.com).
RT #89962: Added support for EA LPC4357 OEM board
RT #89962 EA-LPC4357: SPIFI support, eNVM fix
RT #89962: Build-time option for UART0 to use XTAL
RT #89962: EA LPC4357 fixes
RT #90499: STM-SOM-Rev2A U-boot support
RT #90499 STM-SOM-Rev2A Fixing NOR flash timings
RT #89238. K70: "mtest" end address should account the malloc-ed memory.
RT #90499: STM32F4X9-SOM NOR/SDRAM errata 2.8.7 fix

Copy image from NOR to SDRAM through On-Chip RAM buffer
setting SDRAM to Self-Refresh on each copy.

Implement flash_read16, flash_write16 and flash_write_buffer
to disable/enable SDRAM on flash access.

Start and immediately put SDRAM in self-refresh on start-up for flash
to work correctly.
RT #89962 K70: enable PLL0 to get 48MHz clock for USB-FS

RT #90499. Redo integration of stm-som 1a and 2a:
 make stm-som_config - for 2A
 make stm-som-1a_config - for 1A
RT92026 Skeleton U-Boot port for the STM32F429 Discovery board.
The port tested on the Emcraft STM32F4 SOM Rev 1A.
RT92026 Ported the U-Boot port for the STM32F429 Discover to
the STM32F429 SOM (the Rev 2A STM32F4 SOM). No port to the Discovery yet!
RT92026 Further clean-up of the U-Boot code for the STM32F429 Discovery.
Got rid of the external Flash configuration to simplify
the board specific code.
