configs: am64x_evm_*_defconfig: Rearrange the components in SRAM to satisfy the limitations for USB DFU boot mode For USB DFU boot mode there is a limitation on the load address of boot images that they have to be less than 0x70001000. Therefore, move the SPL_TEXT_BASE address to 0x70000000. Currently ATF is being loaded at 0x70000000, if the SPL is being loaded at 0x70000000 then ATF would overwrite SPL image when loaded. Therefore, move the location of ATF to a latter location in SRAM, past the SPL image. Also rearrange the EEPROM and BSS data on top of ATF. Given below is the placement of various data sections in SRAM ┌──────────────────────────────────────┐0x70000000 │ │ │ │ │ │ │ SPL IMAGE (Max size 1.5 MB) │ │ │ │ │ │ │ ├──────────────────────────────────────┤0x7017FFFF │ │ │ SPL STACK │ │ │ ├──────────────────────────────────────┤0x70192727 │ GLOBAL DATA(216 B) │ ├──────────────────────────────────────┤0x701927FF │ │ │ INITIAL HEAP (32 KB) │ │ │ ├──────────────────────────────────────┤0x7019A7FF │ │ │ BSS (20 KB) │ ├──────────────────────────────────────┤0x7019F7FF │ EEPROM DATA (2 KB) │ ├──────────────────────────────────────┤0x7019FFFF │ │ │ │ │ ATF (123 KB) │ │ │ │ │ ├──────────────────────────────────────┤0x701BEBFB │ BOOT PARAMETER INDEX TABLE (5124 B)│ ├──────────────────────────────────────┤0x701BFFFF │ │ │SYSFW FIREWALLED DUE TO A BUG (128 KB)│ │ │ ├──────────────────────────────────────┤0x701DFFFF │ │ │ DMSC CODE AREA (128 KB) │ │ │ └──────────────────────────────────────┘0x701FFFFF Signed-off-by: Aswath Govindraju <a-govindraju@ti.com> Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Link: https://lore.kernel.org/r/20210604163043.12811-9-a-govindraju@ti.com
