37 * The DRAM Base differs between some models. We cannot use macros for the
38 * CONFIG_FOO defines which contain the DRAM base address since they end
39 * up unexpanded in include/autoconf.mk .

56 * The A80's A1 sram starts at 0x00010000 rather then at 0x00000000 and is
57 * slightly bigger. Note that it is possible to map the first 32 KiB of the
58 * A1 at 0x00000000 like with older SoCs by writing 0x16aa0001 to the
59 * undocumented 0x008000e0 SYS_CTRL register. Where the 16aa is a key and
60 * the 1 actually activates the mapping of the first 32 KiB to 0x00000000.
61 * A64 and H5 also has SRAM A1 at 0x00010000, but no magic remap register
63 * H6 has SRAM A1 at 0x00020000.

108 * for really big kernels, say 256MB for now.
