mtd/spi-nor: Add SPI memory controllers for ASPEED AST2400

2016-01-27T03:13:52+00:00

This driver adds mtd support for spi-nor attached to either or both of the Static Memory Controller (new registers) or the SPI Memory Controller. The Static Memory Controller is the boot soruce for the SOC. The controller supports up to 5 chip selects in any combination of NAND, NOR, and SPI. The memory controller registers were updated in the AST2300 and this fmc binding is for the registers in the new mode. This driver currently supports only SPI-NOR attached memory, but has some considerations to support the others later (including choice of the Kconfig symbol). There is also a similar register set to support the Static Memory Controller in a legacy address mode. That mode is not currently supported because it is expected that the system will run with the fmc binding supporting multiple chip selects. The normal application of the SPI Memory Controller is designated for use by the host system either for video bios or system bios and can be accessed over either an LPC bus and/or a PCIe bus or via a SPI passthough. The SOC can also access this chip for firmware updates when not in passthrough mode. It is expected the passthru mode and the alternate chip select will be controlled by a future pinmux driver. This driver has only been tested with the ast2400 SOC. Signed-off-by: Milton Miller

Documentation: dt: mtd: replace "nor-jedec" binding with "jedec, spi-nor"

2015-05-15T20:04:00+00:00

In commit 8ff16cf77ce3 ("Documentation: devicetree: m25p80: add "nor-jedec" binding"), we added a generic "nor-jedec" binding to catch all mostly-compatible SPI NOR flash which can be detected via the READ ID opcode (0x9F). This was discussed and reviewed at the time, however objections have come up since then as part of this discussion: http://lkml.kernel.org/g/20150511224646.GJ32500@ld-irv-0074 It seems the parties involved agree that "jedec,spi-nor" does a better job of capturing the fact that this is SPI-specific, not just any NOR flash. This binding was only merged for v4.1-rc1, so it's still OK to change the naming. At the same time, let's move the documentation to a better name. Next up: stop referring to code (drivers/mtd/devices/m25p80.c) from the documentation.
