| * | fdt: arm: Drop device tree paddingSimon Glass2015-06-10-1/+2
| | | | | | | | | | | | | | | | | | | | | The 4KB padding doesn't seem necessary since we don't normally adjust the control device tree file within U-Boot. Also drop the memory table space. Signed-off-by: Simon Glass <sjg@chromium.org>
| * | dm: ns16550: Support CONFIG_SYS_NS16550_MEM32 with driver modelSimon Glass2015-06-10-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | This option is used by some boards, so support it with driver model. This is really ugly - we should rewrite this driver once all users are moved to driver model. Signed-off-by: Simon Glass <sjg@chromium.org>

| * | arm: spl: Add an API to detect when U-Boot is started from SPLSimon Glass2015-06-10-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For secure boot systems it is common to have a read-only U-Boot which starts the machine and jumps to a read-write U-Boot for actual booting the OS. This allows the read-write U-Boot to be upgraded without risk of permanently bricking the machine. In the event that the read-write U-Boot is corrupted, the read-only U-Boot can detect this with a checksum and boot into a recovery flow. To support this, add a way to detect when U-Boot is run from SPL as opposed to some other method, such as booted directly (no SPL) or started from another source (e.g. a primary U-Boot). This works by putting a special value in r0. For now we rely on board-specific code to actually check the register and set a flag. At some point this could be generalised, perhaps by using a spare register and passing a flag to _main and/or board_init_f(). This commit does not implement any feature, but merely provides the API for boards to implement. Signed-off-by: Simon Glass <sjg@chromium.org>

* | | blackfin: fix undefined reference to srand and randMasahiro Yamada2015-06-11-1/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 9ba9e85f3f1c (net: Fix NET_RANDOM_ETHADDR dependencies) accidentally dropped CONFIG_LIB_RAND defines for 14 Blackfin boards. Prior to that commit, those boards defined CONFIG_LIB_RAND, but not CONFIG_NET_RANDOM_ETHADDR. So, commit 9ba9e85f3f1c should not have touched them, but in fact it ripped CONFIG_LIB_RAND off from all the header files, which caused undefined reference to srand and rand. CONFIG_LIB_RAND=y must be revived for such boards. BTW, this commit indeed makes it better, but even with this fix, three boards (bf533-stamp, bf538f-ezkit, cm-bf548) still can not build due to region 'ram' overflowed error. This was cause by commit 6eed3786c68c (net: Move the CMD_NET config to defconfigs) because CMD_NET selects NET, and NET selects REGEX. Eventually, some boards were newly enabled with CONFIG_REGEX, increasing the memory footprint. A patch is expected to fix the build error.

| * | | sunxi: Enable CONFIG_SYS_64BIT_LBA when AHCI is usedBernhard Nortmann2015-06-10-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to absence of CONFIG_SYS_64BIT_LBA, u-boot-sunxi currently has no support for the (GPT) partioning scheme of large disks > 2TB. While the AHCI driver seems to handle this nicely, the problem is that lbaint_t values get truncated to 32-bit. This patch sets CONFIG_SYS_64BIT_LBA from sunxi_common.h for all SoCs that support AHCI (CONFIG_SUNXI_AHCI).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present the driver does not properly honour the requested SPI CS deactivation delay since the SPI bus is changed in the claim_bus() method. Everything the claim_bus() method does can be done when the device is probed (setting the speed and mode) and at the start of a new transfer (where the fifo_status is already cleared). So drop this method. Also, until the delay is complete, we should not touch the bus, so make sure that spi_cs_activate() is called before other things are done in the xfer() method.

To pass a printf format string like "foo %d bar\n" via Kconfig to the code. Right now its not possible to use the escape character '\' in Kconfig string values correctly to e.g. set this string value "test output\n". The '\n' will be converted to 'n'. The current implementation removes some of the '\' chars from the input string in conf_set_sym_val(). Examples: '\' -> '' '\\' -> '\' '\\\' -> '\' '\\\\' -> '\\' ... And then doubles the backslash chars in the output string in sym_escape_string_value(). Example: '\' -> '' -> '' '\\' -> '\' -> '\\' '\\\' -> '\' -> '\\' '\\\\' -> '\\' -> '\\\\' ... As you see in these examples, its impossible to generate a single '\' charater in the output string as its needed for something like '\n'. This patch now changes this behavior to not drop some backslashes in conf_set_sym_val() and to not add new backslashes in the resulting output string. Removing the function sym_escape_string_value() completely as its not needed anymore.
