Subject: [PATCH v1 0/2] SPI-NOR add NPCM FIU controller driver
This patch set adds Flash Interface Unit(FIU) SPI-NOR
support for the Nuvoton NPCM Baseboard Management
Controller (BMC).
The FIU supports single, dual or quad communication interface.
the FIU controller can operate in following modes:
- User Mode Access(UMA): provides flash access by using an
indirect address/data mechanism.
- direct rd/wr mode: maps the flash memory into the core
address space.
- SPI-X mode: used for an expansion bus to an ASIC or CPLD.
The NPCM750/730/715/710 supports up to three FIU devices:
- FIU0 supports two chip select.
- FIU3 supports four chip select.
- FIUX supports two chip select.
The NPCM FIU driver tested on NPCM750 evaluation board.
