[RFC PATCH 2/5] mtd: cfi: introduce CFI_FLASH_BANKS
Patrick Delaunay
patrick.delaunay at foss.st.com
Tue Dec 14 17:57:01 CET 2021
Replace CONFIG_SYS_MAX_FLASH_BANKS by CFI_FLASH_BANKS to prepare
Kconfig migration and avoid to redefine CONFIG_SYS_MAX_FLASH_BANKS
in cfi_flash.h.
After this patch CONFIG_SYS_MAX_FLASH_BANKS should be never used in
the cfi code: use CFI_MAX_FLASH_BANKS for struct size or CFI_FLASH_BANKS
for number of CFI banks which can be dynamic.
This patch modify all the files which include mtd/cfi_flash.h.
