[U-Boot] [PATCH 0/3] sf: Update spi-nor framework

[Prabhakar Kushwaha]

SPI-NOR framework currently supports-
 - (1-1-1, 1-1-2, 1-1-4) read protocols
 - read latency(dummy bytes) are hardcoded with the assumption
 that the flash would support it.
 - No support of mode bits.
 - No support of flash size above 128Mib

This patch set add support of 1-2-2, 1-4-4 read protocols. 
It ports Linux commits "mtd: spi-nor: add a stateless method to support
memory size above 128Mib" and "mtd: spi-nor: parse Serial Flash
Discoverable Parameters (SFDP) tables". It enables 4byte address opcode
and run time flash parameters discovery including dummy cycle and mode
cycle.

  sf: Add support of 1-2-2, 1-4-4 IO READ protocols
  sf: add method to support memory size above 128Mib
  sf: parse Serial Flash Discoverable Parameters (SFDP) tables
