New Revision: 49260
Added:
trunk/target/linux/bcm53xx/patches-4.4/820-spi-bcm53xx-let-DT-specify-SPI-device-s-instead-hard.patch
Removed:
trunk/target/linux/bcm53xx/patches-4.4/404-mtd-bcm53xxspiflash-new-driver-for-SPI-flahes-on-Bro.patch
Modified:
trunk/target/linux/bcm53xx/config-4.4
Log:
bcm53xx: switch to m25p80 and drop bcm53xxspiflash
For some time now m25p80 supports 32 MiB flashes and we just needed to
patch spi-nor to support JEDEC incompatible w25q128. Also by switching
to m25p80 we gain accelerated SPI flash reads.
