Since commit d7157ff49a5b ("mtd: rawnand: Use the ECC framework user
input parsing bits"), ECC are broken in FMC2 driver in case of
nand-ecc-step-size and nand-ecc-strength are not set in the device tree.
To avoid this issue, the default settings are now set in
stm32_fmc2_nfc_attach_chip function.

mtd: hyperbus: Fix build failure when only RPCIF_HYPERBUS is enabled 2020-10-12T19:12:08+00:00 Vignesh Raghavendra vigneshr@ti.com 2020-10-12T07:09:58+00:00 6402f4ce95811db7df72244ca84860332e4c2518 commit 5de15b610f78 ("mtd: hyperbus: add Renesas RPC-IF driver") leads to build failure[1] with COMPILE_TEST and RPCIF_HYPERBUS enabled. This is because driver needs functions RENESAS_RPCIF which is only buildable for CONFIG_ARCH_RENESAS. Fix this by dropping COMPILE_TEST from RPCIF_HYPERBUS Kconfig entry. This ensures driver can be built only when RENESAS_RPCIF is also selected.
