arm: dts: renesas: Enable DBSC5 on R-Car R8A78000 X5H Cortex-M33 RSIP port
Bind the DBSC5 DRAM controller driver on boot in board_early_init_r(), which brings up the DBSC5 DRAM controller and its PHY and which enables access to DRAM present on this system. Add default boot command which loads additional bootloader components from HF and UFS storage into SRAM and DRAM, and starts those components on SCP and AP core 0. The system is then capable of reaching U-Boot on the AP core 0. Specifically, the following components are loaded: - SCP firmware, 384 kiB from HF offset 0x4c0000 to SCP STCM - TFA BL31, 256 kiB from UFS0 offset 0x5000 * 4 kiB sectors to DRAM 0x8c200000 - TEE, 2 MiB from UFS0 offset 0x5200 * 4 kiB sectors to DRAM 0x8c400000 - U-Boot, 1 MiB from UFS0 offset 0x7200 * 4 kiB sectors to DRAM 0x8c300000 - IPL parameters table is generated at DRAM address 0x8c100000 Enable pstore command support to allow dumping kernel console from pstore/ramoops, which is convenient for debugging. Use as follows: => pstore set 0x80000000 0x10000 0x400 0x8000 0 0 0 => pstore display console Signed-off-by: Marek Vasut <[email protected]>
