2017-03-14STiH410: Add STi serial driverPatrice Chotard
This patch adds support to ASC (asynchronous serial controller) driver, which is basically a standard serial driver. This IP is common across other STMicroelectronics SoCs Signed-off-by: Patrice Chotard <patrice.chotard@st.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2017-03-14arm: Add support for STMicroelectronics STiH410 socPatrice Chotard
The STiH410 is an advanced multi-HD AVC processor with 3D graphics acceleration and 1.5-GHz ARM Cortex-A9 SMP CPU part of the STiH407 family. It has wide connectivity including USB 3.0, PCI-e, SATA and gigabit ethernet. Signed-off-by: Patrice Chotard <patrice.chotard@st.com>
2017-03-14armv7m: Add SysTick timer driverPhil Edworthy
The SysTick is a 24-bit down counter that is found on all ARM Cortex M3, M4, M7 devices and is always located at a fixed address. The number of reference clock ticks that correspond to 10ms is normally defined in the SysTick Calibration register's TENMS field. However, on some devices this is wrong, so this driver allows the clock rate to be defined using CONFIG_SYS_HZ_CLOCK.

The workaround for ARM errata 725233 had been lost since commit 45bf05854bc94e (armv7: adapt omap3 to the new cache maintenance framework).

2017-03-14arm: omap3: Compile clock.c with -marm option to unbreak OMAP3530Siarhei Siamashka
Boards with OMAP3530 SoC fail to boot since commit bd2c4522c26d5 ("ti: armv7: enable EXT support in SPL (using ti_armv7_common.h)") because it enabled the use of Thumb2 for the SPL. Experiments have shown that the deadlock happens in the prcm_init() function from 'arch/arm/mach-omap2/omap3/clock.c'. This patch enforces the compilation of clock.c source file in ARM mode and makes the deadlock disappear. We are yet to figure out the root cause of the problem. Still this is somewhat better than having non-bootable boards for years. Signed-off-by: Siarhei Siamashka <siarhei.siamashka@gmail.com> Reviewed-by: Tom Rini <trini@konsulko.com>
2017-03-14LS1021ATWR: Modify u-boot size for sd secure bootVinitha Pillai
Raw uboot image is used in place of FIT image in secure boot. The maximum allocated size of raw u-boot bin is 1MB in memory map. Hence , CONFIG_SYS_MONITOR_LEN has been modified to 1 MB. The bootscript (BS_ADDR) and its header (BS_HDR_ADDR) offset on MMC have also been modified to accommodate the increase in uboot size.

2017-03-14armv8: layerscape: Update early MMU for DDR after initializationYork Sun
In early MMU table, DDR has to be mapped as device memory to avoid speculative access. After DDR is initialized, it needs to be updated to normal memory to allow code execution. To simplify the code, dram_init() is moved into a common file as a weak function. Signed-off-by: York Sun <york.sun@nxp.com>

2017-03-14armv8: ls2080a: Drop early MMU for SPL buildYork Sun
Early MMU improves performance especially on emulators. However, the early MMU is left enabled after the first stage of SPL boot. Instead of flushing D-cache and dealing with re-enabling MMU for the second stage U-Boot, disabling it for SPL build simplifies the process. The performance penalty is unnoticeable on the real hardware. As of now, SPL boot is not supported by existing emulators. So this should have no impact on emulators.

2017-03-14armv8: layerscape: Rewrite memory reservationYork Sun
For ARMv8 Layerscape SoCs, secure memory and MC memorey are reserved at the end of DDR. DDR is spit into two or three banks. This patch reverts commit aabd7ddb and simplifies the calculation of reserved memory, and moves the code into common SoC file. Secure memory is carved out first. DDR bank size is reduced. Reserved memory is then allocated on the top of available memory. U-Boot still has access to reserved memory as data transferring is needed. Device tree is fixed with reduced memory size to hide the reserved memory from OS. The same region is reserved for efi_loader. Signed-off-by: York Sun <york.sun@nxp.com>

2017-03-09do_smhload: fix return codeRyan Harkin
do_smhload was using a ulong to store the return value from smh_load_file. That returns an int, where -1 indicates an error. As a ulong will never be negative, smh_load_file errors were not detected and so_smhload always returned zero. Also, when errors were spotted, do_smhload was returning 1, rather than the enumeration CMD_RET_FAILURE (which is also 1).

2017-03-01armv5te: make 'ret lr' produce iinterworking 'bx lr'Albert ARIBAUD
Current ARM assembler helper for the 'return to caller' pseudo-instruction turns 'ret lr' into 'mov pc, lr' for ARMv5TE. This causes the core to remain in its current ARM state even when the routine doing the 'ret' was called from Thumb-1 state, triggering an undefined instruction exception. This causes early run-time failures in all boards compiled using the Thumb-1 instruction set (for instance the Open-RD family). ARMv5TE supports 'bx lr' which properly implements interworking and thus correctly returns to Thumb-1 state from ARM state. This change makes 'ret lr' turn into 'bx lr' for ARMv5TE.

2017-02-23ARM: uniphier: deassert RST_n of eMMC device for LD11/LD20Masahiro Yamada
For LD11 and LD20 SoCs, the RST_n pin is asserted by default. If the EXT_CSD[162], bit[1:0] (RST_n_ENABLE) is fused, the eMMC device would stay in the reset state until its RST_n pin is deasserted by software.
