2014-01-15Intel (sandy/ivy): Avoid calling cbmem_initialize() twiceKyösti Mälkki
Delay the copying of MRC cache data from CAR to CBMEM until after sdram_initialize() returns and cbmem_initialize() completes. Calling cbmem_initialize() twice would complicate the decision logic of when CBMEM area needs to be wiped clean.

2014-01-15Re-declare CACHE_ROM_SIZE as aligned ROM_SIZE for MTRRKyösti Mälkki
This change allows Kconfig options ROM_SIZE and CBFS_SIZE to be set with values that are not power of 2. The region programmed as WB cacheable will include all of ROM_SIZE. Side-effects to consider: Memory region below flash may be tagged WRPROT cacheable. As an example, with ROM_SIZE of 12 MB, CACHE_ROM_SIZE would be 16 MB. Since this can overlap CAR, we add an explicit test and fail on compile should this happen. To work around this problem, one needs to use CACHE_ROM_SIZE_OVERRIDE in the mainboard Kconfig and define a smaller region for WB cache. With this change flash regions outside CBFS are also tagged WRPROT cacheable. This covers IFD and ME and sections ChromeOS may use.

PLL5 is special in that it controls the DRAM clock, and requires a fine-grained low-level control which will be needed by raminit code. This change also brings functionality which will be needed by raminit.

2014-01-09cubieboard: Initialize memory in bootblockAlexandru Gagniuc
Even though the Allwinner A10 is limited to a 24KiB bootblock, the memory initialization takes only about 3KiB and leaves enough room for an MMC or NAND driver, so init the memory early on. The advantage is that we can eliminate complicated logistics of where to cache CBFS and where to load the ramstage in SRAM.

2014-01-09cubieboard: Keep AHB clock within specsAlexandru Gagniuc
The CPU was clocked at 384MHz in the bootblock, but the AHB bus has a maximum rated frequency of 250MHz. Its clock needs to be divided to keep it within spec. Overclocking the AHB bus hung the CPU when memory was accessed.
