2020-10-12mtd: hyperbus: Fix build failure when only RPCIF_HYPERBUS is enabledVignesh Raghavendra
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.

2020-10-02mtd: parsers: bcm63xx: Do not make it modularFlorian Fainelli
With commit 91e81150d388 ("mtd: parsers: bcm63xx: simplify CFE detection"), we generate a reference to fw_arg3 which is the fourth firmware/command line argument on MIPS platforms. That symbol is not exported and would cause a linking failure. The parser is typically necessary to boot a BCM63xx-based system anyway so having it be part of the kernel image makes sense, therefore make it 'bool' instead of 'tristate'.

2020-10-02mtd: physmap: Add Baikal-T1 physically mapped ROM supportSerge Semin
Baikal-T1 Boot Controller provides an access to a RO storages, which are physically mapped into the SoC MMIO space. In particularly there are Internal ROM embedded into the SoC with a pre-installed firmware, externally attached SPI flash (also accessed in the read-only mode) and a memory region, which mirrors one of them in accordance with the currently enabled system boot mode (also called Boot ROM). This commit adds the Internal ROM support to the physmap driver of the MTD kernel subsystem. The driver will create the Internal ROM MTD as long as it is defined in the system dts file. The physically mapped SPI flash region will be used to implement the SPI-mem interface. The mirroring memory region won't be accessible directly since it's redundant due to both bootable regions being exposed anyway. Note we had to create a dedicated code for the ROMs since read from the corresponding memory regions must be done via the dword-aligned addresses.
