2014-07-14AMD SPI: Optimise for longer writesKyösti Mälkki
Leave it to the implementation of flash->write() to split the writes to match SPI controller and SPI flash part restrictions. This allows for some optimisation for auto-address-increment (AAI) commands. Kconfig AMD_SB_SPI_TX_LEN can be kept as local.

2014-07-03AGESA: Clean separation of SPI flashKyösti Mälkki
To be precise, wakeup from S3 does not involve SPI writing, while preparing for it on cold power-ons currently does. For S3DataTypeMtrr storage is changed such that the first 4 bytes is the length of data stored like with the other two S3DataType.
