* 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
