AST2700 is the 8th generation of Integrated Remote Management
Processor introduced by ASPEED Technology Inc. It is a Board
Management Controller (BMC) SoC family with a dual-die architecture:
SoC0 ("CPU" die with four ARM Cortex-A35 application cores) and
SoC1 ("IO" die with peripherals) each SoC have its own SCU PLLs,
clock dividers and reset domains.Signed-off-by: Ryan Chen <[email protected]> --- Changes in v4: - Rebase onto latest master. - spi: add AST2700 support to the spi-aspeed-smc driver, rework AHB addresses to uintptr_t for the 64-bit AST2700. - configs: enable SPI flash support in evb-ast2700_defconfig. - Link to v3: https://lore.kernel.org/r/[email protected] Changes in v3: - mach: add "N: ast2700" to the ARM ASPEED MAINTAINERS entry. - Link to v2: https://lore.kernel.org/r/[email protected] Changes in v2: - v1 only have clk driver, v2 apply full AST2700 platform and reset, clk, ram driver. - Move scu_ast2700.h from the clk patch into the mach-aspeed - patch so the SoC header is provided alongside the SoC code that consumes it.
