2020-10-12mtd: hyperbus: Fix build failure when only RPCIF_HYPERBUS is enabledVignesh Raghavendra1-1/+1
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.

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 Semin5-0/+160
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.

2020-09-30mtd: rawnand: atmel: Use nand_{write,read}_data_op()Boris Brezillon1-5/+5
Use the nand_{write,read}_data_op() helpers instead of calling the atmel_nand_{read,write}_buf() functions directly. This will ease the transition to exec_op().

The legacy page read path in atmel_hsmc_nand_pmecc_read_pg() issues a nand_read_page_op() that's already issued by atmel_nand_pmecc_read_pg(). Let's get rid of the unneeded one.

2020-09-30mtd: rawnand: atmel: Enable the NFC controller at probe timeBoris Brezillon1-6/+6
No need to enable it everytime select_chip() is called. If we really care about PM, we should implement runtime PM hooks and disable the controller and all its clocks when the controller has been unused for some time.

2020-09-30mtd: rawnand: Use the ECC framework user input parsing bitsMiquel Raynal1-72/+70
Many helpers are generic to all NAND chips, they should not be raw-NAND specific, so use the generic ones. To avoid moving all the raw NAND core "history" into the generic NAND layer, we keep a part of this parsing in the raw NAND core to ensure backward compatibility.

2020-09-30mtd: hyperbus: hbmc-am654: Add DMA support for readsVignesh Raghavendra1-1/+125
AM654 HyperBus controller provides MMIO interface to read data from flash. So add DMA memcpy support for reading data over MMIO interface. This provides 5x improvement in throughput and reduces CPU usage as well.
