A set of SPI flash slaves is attached under the flash controllers of the palmetto platform. "n25q256a" flash modules are used for the BMC and "mx25l25635e" for the host. These types are common in the OpenPower ecosystem. Signed-off-by: Cédric Le Goater <clg@kaod.org> --- Changes since v3 : - moved memory mapping to platform initialization Changes since v2 : - moved the initialization of the flash modules under the palmetto platform hw/arm/palmetto-bmc.c | 31 +++++++++++++++++++++++++++++++ 1 file changed, 31 insertions(+)
