2015-01-13arm: am437x: Enable hardware leveling for EMIFJames Doublesin
Switch to using hardware leveling for certain parameters on the EMIF rather than using precalculated values. Doing this also means we have a common place now between am437x and am335x for setting emif_sdram_ref_ctrl with a value for the correct delay length.

2015-01-09arm: build arch memset/memcpy in Thumb2 modeStefan Agner
Resynchronize memcpy/memset with kernel 3.17 and build them in Thumb2 mode (unified syntax). Those assembler files can be built and linked in ARM mode too, however when calling them from Thumb2 built code, the stack got corrupted and the copy did not succeed (the exact details have not been traced back). However, the Linux kernel builds those files in Thumb2 mode. Hence U-Boot should build them in Thumb2 mode too when CONFIG_SYS_THUMB_BUILD is set. To build the files without warning, some assembler instructions had to be replaced with their UAL compliant variant (thanks Jeroen for this input). To build the file in Thumb2 mode the implicit-it=always option need to be set to generate Thumb2 compliant IT instructions where needed. We add this option to the general AFLAGS when building for Thumb2. Reviewed-by: Simon Glass <sjg@chromium.org> Tested-by: Simon Glass <sjg@chromium.org> Signed-off-by: Stefan Agner <stefan@agner.ch>

The low-level debugging functions are useful to debug the early boot stage where the full UART driver is not available. UniPhier SoCs need to initialize the UART port 0 to use this feature.

2015-01-05ARM: OMAP4: Panda: rework DMM logicNishanth Menon
Part of DMM logic is reuse from commit 47a4bea6af77b01d59a410d09a4c34b2dd14cf50 ("ARM: omap4: Update sdram setting for panda rev A6") Which broke SDP4430 with ES2.3 (uses old DDR). So, to maintain support for newer DDR used in Panda ES rev B3, we should, in addition to the commit 675cc77a3ae45e8b0ec17128563264d4a509f628 ("ARM:OMAP4+: panda-es: Support Rev B3 Elpida DDR2 RAM"), DDR timings, also do DMM configuration specific to Panda.

2015-01-05ARM: bootm: do not add PSCI to fdt when booting in secure mode.Ian Campbell
Commit 8bc347e2ec17 "ARM: bootm: Allow booting in secure mode on hyp capable systems" added the capability to select nonsec vs sec mode boot via an environment var. There is a subtle gotcha with this functionality, which is that the PSCI nodes are still created in the fdt (via armv7_update_dt->fdt_psci) even when booting in secure mode. Which means that if the kernel is PSCI aware then it will fail to boot because it will try and do PSCI from secure world, which won't work. This likely didn't get noticed before because the original purpose was to support booting the legacy linux-sunxi kernels which don't understand PSCI. To fix expose boot_nonsec (renaming with armv7_ prefix) outside of bootm.c and use from the virt-dt code. As well as avoiding the creation of the PSCI nodes we should also avoid reserving the secure RAM, so do so.

2014-12-29arm: semihosting: fix up compile bugsLinus Walleij
There is currently a regression when using newer ARM64 compilers for semihosting: the way long types are inferred from context is no longer the same. The semihosting runtime uses long and size_t, so use this explicitly in the semihosting code and interface, and voila: the code now works again.

2014-12-29arm: semihosting: staticize internal functionsLinus Walleij
The semihosting code exposes internal file handle handling functions to read(), open(), close() and get the length of a certain file handle. However the code using it is only interested in either reading and entire named file into memory or getting the file length of a file referred by name. No file handles are used. Thus make the file handle code internal to this file by removing these functions from the semihosting header file and staticize them. This gives us some freedom to rearrange the semihosting code without affecting the external interface.

2014-12-18ARM: Implement non-cached memory supportThierry Reding
Implement an API that can be used by drivers to allocate memory from a pool that is mapped uncached. This is useful if drivers would otherwise need to do extensive cache maintenance (or explicitly maintaining the cache isn't safe). The API is protected using the new CONFIG_SYS_NONCACHED_MEMORY setting. Boards can set this to the size to be used for the non-cached area. The area will typically be right below the malloc() area, but architectures should take care of aligning the beginning and end of the area to honor any mapping restrictions. Architectures must also ensure that mappings established for this area do not overlap with the malloc() area (which should remain cached for improved performance). While the API is currently only implemented for ARM v7, it should be generic enough to allow other architectures to implement it as well.

2014-12-09ARM: UniPhier: detect the number of flash banks at run-timeMasahiro Yamada
Some UniPhier boards are equipped with an expansion slot that some optional SRAM/NOR-flash cards can be attached to. So, run-time detection of the number of flash banks would be more user-friendly. Until this commit, UniPhier boards have achieved this by (ab)using board_flash_wp_on() because the boot failed if flash_size got zero. Fortunately, this problem was solved by commit 70879a92561a (flash: do not fail even if flash_size is zero). Now it is possible to throw away such a tricky workaround. This commit also enables CONFIG_SYS_MAX_FLASH_BANKS_DETECT for further refactoring. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2014-12-08ARM: rpi_b: detect board revisionStephen Warren
Detect the board revision early during boot, and print the decoded model name. Eventually, this information can be used for tasks such as: - Allowing/preventing USB device mode; some models have a USB device on- board so only host mode makes sense. Others connect the SoC directly to the USB connector, so device-mode might make sense. - The on-board USB hub/Ethernet requires different GPIOs to enable it, although luckily the default appears to be fine so far. - The compute module contains an on-board eMMC device, so we could store the environment there. Other models use an SD card and so don't support saving the environment (unless we store it in a file on the FAT boot partition...) Set $fdtfile based on this information. At present, the mainline Linux kernel doesn't contain a separate DTB for most models, but I hope that will change soon.
