Since we use CONFIG_SYS_GENERIC_BOARD on x86, we don't need this anymore.

- * Getting the board up and running is a three-stage process:
- * 1) Execute from Flash, SDRAM Uninitialised
- * At this point, there is a limited amount of non-SDRAM memory
- * (typically the CPU cache, but can also be SRAM or even a buffer of
- * of some peripheral). This limited memory is used to hold:
- * - The initial copy of the Global Data Structure
- * - A temporary stack
- * - A temporary x86 Global Descriptor Table
- * - The pre-console buffer (if enabled)
- *
- * The following is performed during this phase of execution:
- * - Core low-level CPU initialisation
- * - Console initialisation
- * - SDRAM initialisation
- *
- * 2) Execute from Flash, SDRAM Initialised
- * At this point we copy Global Data from the initial non-SDRAM
- * memory and set up the permanent stack in SDRAM. The CPU cache is no
- * longer being used as temporary memory, so we can now fully enable
- * it.
- *
- * The following is performed during this phase of execution:
- * - Create final stack in SDRAM
- * - Copy Global Data from temporary memory to SDRAM
- * - Enabling of CPU cache(s),
- * - Copying of U-Boot code and data from Flash to RAM
- * - Clearing of the BSS
- * - ELF relocation adjustments
- *
- * 3) Execute from SDRAM
- * The following is performed during this phase of execution:
- * - All remaining initialisation
