For both AST2500 and AST2600, there are three SPI controllers, FMC(Firmware Memory Controller), SPI1 and SPI2. The clock source is HCLK. Following is the basic information for ASPEED SPI controller. AST2500: - FMC: CS number: 3 controller reg: 0x1e620000 - 0x1e62ffff decoded address: 0x20000000 - 0x2fffffff - SPI1: CS number: 2 controller reg: 0x1e630000 - 0x1e630fff decoded address: 0x30000000 - 0x37ffffff - SPI2: CS number: 2 controller reg: 0x1e631000 - 0x1e631fff decoded address: 0x38000000 - 0x3fffffff AST2600: - FMC: CS number: 3 controller reg: 0x1e620000 - 0x1e62ffff decoded address: 0x20000000 - 0x2fffffff - SPI1: CS number: 2 controller reg: 0x1e630000 - 0x1e630fff decoded address: 0x30000000 - 0x3fffffff - SPI2: CS number: 3 controller reg: 0x1e631000 - 0x1e631fff decoded address: 0x50000000 - 0x5fffffff Signed-off-by: Chin-Ting Kuo <chin-ting_kuo@aspeedtech.com>
