Falcon mode entails the SPL booting the OS directly instead of U-Boot. Signed-off-by: Tim Harvey <tharvey@gateworks.com>
2015-05-21wandboard: Switch to SPL supportFabio Estevam
Currently we need to build one U-boot image for each of the wandboard variants: quad, dual-lite and solo. By switching to SPL we can support all these variants with a single binary, which is very convenient. Based on the work from Richard Hu. Tested kernel booting on the three boards.

2015-05-19imx: mx6: add get_cpu_temp_grade to obtain cpu temperature grade from OTPTim Harvey
The MX6 has a temperature grade defined by OCOTP_MEM0[7:6] which is at 0x480 in the Fusemap Description Table in the reference manual. Return this value as well as min/max temperature based on the value. Note that the IMX6SDLRM and the IMX6SXRM do not indicate this in the their Fusemap Description Table however Freescale has confirmed that these eFUSE bits match the description within the IMX6DQRM and that they will be added to the next revision of the respective reference manuals.

The IMX6 has four different speed grades determined by eFUSE SPEED_GRADING indicated by OCOTP_CFG3[17:16] which is at 0x440 in the Fusemap Description Table. Return this frequency so that it can be used elsewhere. Note that the IMX6SDLRM and the IMX6SXRM do not indicate this in the their Fusemap Description Table however Freescale has confirmed that these eFUSE bits match the description within the IMX6DQRM and that they will be added to the next revision of the respective reference manuals.

2015-05-19arm: mx6: ddr: set fast-exit on DDR3 if pd_fast_exit specifiedTim Harvey
Commit fa8b7d66f49f0c7bd41467fe78f6488d8af6976a introduced fast-exit support to the MMDC however enabling it on the DDR3 got missed. Make sure we enable it on the DDR3 as well. Gateworks uses Micron memory as well as Winbond in MX6. We have found in testing that we need to enable fast-exit for Winbond stability. Gateworks boards are currently the only boards using the MX6 SPL and enabling fast-exit mode. Signed-off-by: Tim Harvey <tharvey@gateworks.com>

2015-05-19env_nand: use nand_spl_load_image for readenv if SPLTim Harvey
The readenv() implementation of env_nand uses the mtd layer which is unnecessary overhead in SPL when we already have a nand_spl_load_image() function that doesn't need it. Using this instead eliminates the need to provide a mtd_read for SPL env as well as reduces code (4KB savings in IMX6 SPL).

2015-05-15mx6: Set shared override bit in PL310 AUX_CTRL registerFabio Estevam
Having bit 22 cleared in the PL310 Auxiliary Control register (shared attribute override enable) has the side effect of transforming Normal Shared Non-cacheable reads into Cacheable no-allocate reads. Coherent DMA buffers in Linux always have a Cacheable alias via the kernel linear mapping and the processor can speculatively load cache lines into the PL310 controller. With bit 22 cleared, Non-cacheable reads would unexpectedly hit such cache lines leading to buffer corruption. This was inspired by a patch from Catalin Marinas [1] and also from recent discussions in the linux-arm-kernel list [2] where Russell King and Rob Herring suggested that bootloaders should initialize the cache.
