soc: aspeed: socinfo: Add new systems
Aspeed's u-boot sdk has been updated with the SoC IDs for the AST2605 variant, as well as A2 and A3 variants of the 2600 family. >From u-boot's arch/arm/mach-aspeed/ast2600/scu_info.c: SOC_ID("AST2600-A0", 0x0500030305000303), SOC_ID("AST2600-A1", 0x0501030305010303), SOC_ID("AST2620-A1", 0x0501020305010203), SOC_ID("AST2600-A2", 0x0502030305010303), SOC_ID("AST2620-A2", 0x0502020305010203), SOC_ID("AST2605-A2", 0x0502010305010103), SOC_ID("AST2600-A3", 0x0503030305030303), SOC_ID("AST2620-A3", 0x0503020305030203), SOC_ID("AST2605-A3", 0x0503010305030103), Fixes: e0218dca5787 ("soc: aspeed: Add soc info driver") Link: https://lore.kernel.org/r/20210210114651.334324-1-joel@jms.id.au Signed-off-by: Joel Stanley <joel@jms.id.au>
