Subject: bcm53xx: switch to m25p80 and drop bcm53xxspiflash
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=741715331aeec9621d15ec55f8385910b341fbe2;p=openwrt%2Fstaging%2Fadrian.git
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.
