spi: fsl-cpm: Use 16 bit mode for large transfers with even size
On CPM, the RISC core is a lot more efficiant when doing transfers in 16-bits chunks than in 8-bits chunks, but unfortunately the words need to be byte swapped as seen in a previous commit.
So, for large tranfers with an even size, allocate a temporary tx buffer and byte-swap data before and after transfer.
This change allows setting higher speed for transfer. For instance on an MPC 8xx (CPM1 comms RISC processor), the documentation tells that transfer in byte mode at 1 kbit/s uses 0.200% of CPM load at 25 MHz while a word transfer at the same speed uses 0.032% of CPM load. This means the speed can be 6 times higher in word mode for the same CPM load.
For the time being, only do it on CPM1 as there must be a trade-off between the CPM load reduction and the CPU load required to byte swap the data.

spi: fsl-spi: use devm_ioremap_resource() to map parameter ram on CPM1
On CPM2, the SPI parameter RAM is dynamically allocated in the dualport RAM whereas in CPM1, it is statically allocated to a default address with capability to relocate it somewhere else via the use of CPM micropatch. The address of the parameter RAM is given by the boot loader and expected to be mapped via devm_ioremap_resource()
In the current implementation, in function fsl_spi_cpm_get_pram() there is a confusion between the SPI_BASE register and the base of the SPI parameter RAM. Fortunatly, it is working properly with MPC866 and MPC885 because they do set SPI_BASE, but on MPC860 and other old MPC8xx that doesn't set SPI_BASE, pram_ofs is not properly set. Also, the parameter RAM is not properly mapped with devm_ioremap_resource() as it should but still gets accessible by chance through the full RAM which is mapped from somewhere else.
This patch applies to the SPI driver the same principle as for the CPM UART: when the CPM is of type CPM1, we simply do an devm_ioremap_resource() of the area provided via the device tree.

spi: fsl-spi: Don't use cpm_command on CPM1
On CPM1, when the SPI parameter RAM is relocated to somewhere else than the default location, in accordance with freescale documentation (refer micropatch SPI application note EB662), init RX/TX params command shall not be used because it doesn't take into account the new location, and overwrites data that is in original location of SPI param ram at addresses SCC2 param base + (u32*)0x88 (u16*)0x90 (u32*)0x98 (u16*)0xA0, hence breaking activity on SCC2 if SCC2 is used in a mode like QMC for instance.
Therefore, the action shall be done manually as described by freescale and as was already partly done by the driver.

spi: fsl: Sort include headers alphabetically
Sort all the include headers alphabetically for the freescale spi drivers. If the inlcude headers sorted out of order, maybe the best logical choice is to append new ones after the exist ones, while this may create a lot of potential for duplicates and conflicts for each diffenent changes will add new headers in the same location.

spi/spi-fsl-spi: Make driver usable in CPU mode outside of an FSL_SOC environment
This makes the spi-fsl-spi driver usable in CPU mode outside of an FSL_SOC and even an powerpc environment by moving CPM mode functionality to a separate file that is only compiled and linked in an FSL_SOC environment and adding some ifdefs to hide types and functions or provide alternatives.
For devicetree probing a "clock-frequency" property is used for clock frequency instead of calls to FSL_SOC-specific functions.

spi: fsl-spi: use devm_ioremap_resource() to map parameter ram on CPM1 On CPM2, the SPI parameter RAM is dynamically allocated in the dualport RAM whereas in CPM1, it is statically allocated to a default address with capability to relocate it somewhere else via the use of CPM micropatch. The address of the parameter RAM is given by the boot loader and expected to be mapped via devm_ioremap_resource() In the current implementation, in function fsl_spi_cpm_get_pram() there is a confusion between the SPI_BASE register and the base of the SPI parameter RAM. Fortunatly, it is working properly with MPC866 and MPC885 because they do set SPI_BASE, but on MPC860 and other old MPC8xx that doesn't set SPI_BASE, pram_ofs is not properly set. Also, the parameter RAM is not properly mapped with devm_ioremap_resource() as it should but still gets accessible by chance through the full RAM which is mapped from somewhere else. This patch applies to the SPI driver the same principle as for the CPM UART: when the CPM is of type CPM1, we simply do an devm_ioremap_resource() of the area provided via the device tree.

spi: fsl-spi: Don't use cpm_command on CPM1 On CPM1, when the SPI parameter RAM is relocated to somewhere else than the default location, in accordance with freescale documentation (refer micropatch SPI application note EB662), init RX/TX params command shall not be used because it doesn't take into account the new location, and overwrites data that is in original location of SPI param ram at addresses SCC2 param base + (u32*)0x88 (u16*)0x90 (u32*)0x98 (u16*)0xA0, hence breaking activity on SCC2 if SCC2 is used in a mode like QMC for instance. Therefore, the action shall be done manually as described by freescale and as was already partly done by the driver.
