This patch Enable ARM L2 cache module in Nuvoton NPCM7xx BMC by adding L2 cache parameters into NPCM7xx DT machine start structure. At patch V7 arm: npcm: add basic support for Nuvoton BMCs we got comments regarding the flags use in L2 cache module. - https://www.spinics.net/lists/arm-kernel/msg613212.html After checking again the L2 cache use in the NPCM7xx, the only L2 cache flag we need to set is L2C_AUX_CTRL_SHARED_OVERRIDE and it is done in the device tree: https://patchwork.kernel.org/patch/10063497/ L2 cache flag mask allowed all the flag option.
