Subject: [U-Boot] [PATCH 0/3] mtd: spi: Add MSCC SPI flash driver
Date: Wed, 16 Jan 2019 13:07:52 +0100	[thread overview]
Message-ID: <1547640475-26939-1-git-send-email-horatiu.vultur@microchip.com> (raw)

This patch series adds MSCC SPI flash driver. The VCore III SoCs can access
directly the flash through memory, this direct mapping is working only for
read functions. The other operations are going through SPI driver.

This improves the read performace by a factor of 4.75.

This patch series is based on u-boot-mips/next.

Horatiu Vultur (3):
  mtd: spi: export functions to sf_internal.h
  mtd: spi: add MSCC SPI flash driver
  mips: mscc: use MSCC SPI flash driver for Luton
