To support the SPI MEM API, instead of modifying the existing U-Boot driver, this patch adds a port of the existing Linux driver. This also has the advantage that porting changes and fixes from Linux will be easier. Porting of driver left most of the functions unchanged while few of the changes are: -Remove lock(mutexes) and irq handler as u-boot is a single core execution. -Remove invalid masterid as it was required specially for multicore execution in LS2088ARDB which is not the case in u-boot. -Remove clock support as changing spi speed is not supported in uboot and nor in linux.

Currently tested on LS1088ARDB, LS1012ARDB, LS1046ARDB, LS1046AFRWY, LS1043AQDS, LS1021ATWR, LS2088ARDB, I.MX6ULL EVK.

From: Frieder Schrempf frieder.schrempf@kontron.de

This property is not used by the driver anymore so let's remove it. Other dts still have 'num-cs' set, but they need a resync with the Linux kernel anyway, so let's only do the U-Boot-specific files for now.

Since CONFIG_FSL_QSPI is already enabled for LS1012A in defconfigs. Also enable CONFIG_SPI_FLASH_SPANSION for LS1012A boards having spansion flashes.

According to new qspi driver, some properties like "bus-num, num-cs, big-endian" are no longer used. Device endiannes can be determined from device-type data in driver.

Now use board specific compatibles, generic node names and specific labels to align with linux device-tree properties.

Also consolidate spi-max-frequency to 50Mhz treewide.
