41 * up unexpanded in include/autoconf.mk .

58 * The A80's A1 sram starts at 0x00010000 rather then at 0x00000000 and is
59 * slightly bigger. Note that it is possible to map the first 32 KiB of the
60 * A1 at 0x00000000 like with older SoCs by writing 0x16aa0001 to the
61 * undocumented 0x008000e0 SYS_CTRL register. Where the 16aa is a key and
62 * the 1 actually activates the mapping of the first 32 KiB to 0x00000000.
