* tegra: clock: Split the clock source code into a separate functionSimon Glass2015-05-13-22/+40
| | | | | | | | | Create a function which sets the source clock for a peripheral, given the number of mux bits to adjust. This can then be used more generally. For now, don't export it. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>

| | | | | | | | | The get_pll() function can do the wrong thing if passed values that are out of range. Add checks for this and add a function which can return a 'simple' PLL. This can be defined by SoCs with their own clocks. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>

* Clean all defconfigs with savedefconfigJoe Hershberger2015-05-12-1614/+1335
| | | | | | | | | | | | | In order to reduce merge conflicts and to maintain the simplest possible defconfig files, we should be using the savedefconfig feature of Kconfig every time a new feature is added. This keeps the defconfig settings to a minimum (only those things not default) and keeps them in the same order as the Kconfig options.

This will also enable us to remove the CONFIG_AUTOBOOT_DELAY_STR2 and CONFIG_AUTOBOOT_STOP_STR2 macros, as this sc3 board is the only one using one of this macros. A removal patch will follow soon.

* Fix broken verify functionality in crc32 commandJoe Hershberger2015-05-10-1/+1
| | | | | | | | | | | | | | Introduced in change d20a40de9db07de1f1f06a79a4da1cdda5379b75 "Roll crc32 into hash infrastructure" The crc32 command with no -v expects an optional 3rd argument to be an address to store the result in. With the -v switch, the last argument is a crc, not an address. In the case where -v is set, we should set the HASH_FLAG_ENV flag since that will first look for the value to be a digest value, which matches the expected API for the crc32 command.

* overo: Fix regression introduced in a6b541bArun Bharadwaj2015-05-10-14/+0
| | | | | | | | | | | | | | | | U-Boot has been broken on Overo boards since commit a6b541b09022acb6f7c2754100ae26bd44eed1d9. This is because the gd pointer is not set early enough anymore, such that the i2c_set_bus_num in get_board_revision can safely execute. This results in a console hang at SPL and the boot does not proceed. This piece of code is anyway necessary only for really old Overo boards with revision numbers <= 2410 and not required for the newer boards. For these older boards, u-boot v2014.10 still works fine.

| | | | | | | | | | If regular NAND booting fails to find a valid uImage in the kernel partition in NAND, try to boot using a zImage and dtb found in a UBI volume in the rootfs partition.

* omap3: overo: Use software BCH8 ECC for NANDAsh Charles2015-05-10-4/+15
| | | | | | | | | | | | | | | | | | | | | Overo COMs have NAND flash that requires 4-bit ECC or better except for the first sector which can use 1-bit ECC. The boot ROM expects to load a payload from NAND written using 1-bit hardware-based ECC. In short, write SPL to NAND something like this (4 times for redundancy): #> nandecc hw #> nand write ${loadaddr} 0x0 ${filesize} #> nand write ${loadaddr} 0x20000 ${filesize} #> nand write ${loadaddr} 0x40000 ${filesize} #> nand write ${loadaddr} 0x60000 ${filesize} Then, switch back to software-based BCH8 for everything else: #> nandecc sw bch8 After [1], enlarge the max size of the SPL so the BCH code can fit.

| | | | | | | | | | | | | | | | | | | | | | | Since the used AM3352 SoC doesn't have GPU it isn't allways necessary to build in complete drm-stuff into linux kernel. In very small applications only we use the simple-framebuffer. So we have 2 use-cases: - device operating on drm-driver (let simplefb node disabled) - device operating on simplefb-driver (activate simplefb node and reserve mem) The decision is made by means of "simplefb" environment variable. simplefb = 0 we don't enable the (maybe) existing simplefb node and all the rest around display is up to the linux-kernel. We just disable the backlight, beceause we do not want see the flicker during take over of drm-driver. simplefb = 1 we enable the (maybe) existing simplefb node and reserve framebuffers size in memory.

* image: android: handle default kernel addressMaxime Ripard2015-05-08-2/+25
| | | | | | | | | | | | | | | | | | The two tools that create android boot images, mkbootimg and the fastboot client, set the kernel address by default to 0x10008000. U-boot always honors this field, and will try to relocate the kernel to whatever value is set in the header, which won't be mapped to the actual RAM on most platforms, resulting in the kernel obviously not booting. All the targets in U-Boot right now will download the android boot image to CONFIG_SYS_LOAD_ADDR, which means that it will already have been downloaded to some location that is suitable for execution. In order to have the kernel booting even with the default boot image kernel address, if that address is used, just execute the kernel where it is.
