Introduce EN7581 SoC support with currently rfb board supported. This is a new 64bit SoC from Airoha that is currently almost fully supported upstream with only the DTS missing. Setting source-only waiting for the full upstream support to be completed. Link: https://github.com/openwrt/openwrt/pull/16730 Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>

Subject: [PATCH 1/2] spi: airoha: fix dirmap_{read,write} operations
|
|
|
|
SPI_NFI_READ_FROM_CACHE_DONE bit must be written at the end of
|
|
dirmap_read operation even if it is already set.
|
|
In the same way, SPI_NFI_LOAD_TO_CACHE_DONE bit must be written at the
|
|
end of dirmap_write operation even if it is already set.
|
|
For this reason use regmap_write_bits() instead of regmap_set_bits().
|
|
This patch fixes mtd_pagetest kernel module test.
