The size of the installed SRAM memory is required in order to

properly configure memory mapping. The mapping will begin at the

start of SDRAM plus AM335X_DDR_MAPOFFSET and extend for DDR_MAPSIZE

the full, installed size of the DRAM. But these values can be

modified to set aside memory at the beginning or end of SRAM that is

unmapped (or mapped differently). NOTE also that this value relates

closely to other settings:

RAM_START and RAM_VSTART give this physical and virtual addresses
|
|
of the start of usable memory (beginning with .text). NOTE that

this may not necessarily be the actual start of the mapped SDRAM

region. It will be larger if NuttX begins at an offset from

beginning of mapped SDRAM (which is the normal case).

RAM_SIZE gives the size of the .text, .data, and .bss sections
