* kconfig: remove redundant "string" type in arch and board KconfigsMasahiro Yamada2014-09-13603-2161/+0
| | | | | | | | | | | | | | | | | | Now the types of CONFIG_SYS_{ARCH, CPU, SOC, VENDOR, BOARD, CONFIG_NAME} are specified in arch/Kconfig. We can delete the ones in arch and board Kconfig files. This commit can be easily reproduced by the following command: find . -name Kconfig -a ! -path ./arch/Kconfig | xargs sed -i -e ' /config[[:space:]]SYS_\(ARCH\|CPU\|SOC\|\VENDOR\|BOARD\|CONFIG_NAME\)/ { N s/\n[[:space:]]*string// } ' Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* kconfig: add CONFIG_SYS_{ARCH, CPU, ...} type def to arch/KconfigMasahiro Yamada2014-09-131-0/+56
| | | | | | | | | This commit adds the type definitions (+ help messages) of CONFIG_SYS_{ARCH, CPU, SOC, VENDOR, BOARD, CONFIG_NAME} to arch/Kconfig, which would save lots of type defs for taget boards. (See also the next commit.) Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

| * dm: tegra: Enable driver model for serialSimon Glass2014-09-103-1/+47
| | | | | | | | | | | | | | | | | | Use driver model for serial ports. Since Tegra now uses driver model for serial, adjust the definition of V_NS16550_CLK so that it is clear that this is only used for SPL. Signed-off-by: Simon Glass <sjg@chromium.org>
| * tegra: dts: Add serial port detailsSimon Glass2014-09-1024-10/+1405
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some Tegra device tree files do not include information about the serial ports. Add this and also add information about the input clock speed. The console alias needs to be set up to indicate which port is used for the console. Also add a binding file since this is missing. Series-changes; 5 - Add full serial port nodes from Linux tree (commit fc9d4dbe) - Use /chosen/stdout-path instead of /aliases/console to specify the console Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | | | | Add driver model support so that ns16550 can support operation both with and without driver model. The driver needs a clock frequency so cannot stand alone unfortunately. The clock frequency must be provided by a separate driver. Signed-off-by: Simon Glass <sjg@chromium.org>

| * sandbox: serial: Support a coloured consoleSimon Glass2014-09-101-0/+83
| | | | | | | | | | | | | | | | | | | | The current sandbox serial driver is a pretty trivial example and does not have the featues that might be needed for other board serial drivers. To help provide a better example, add a text colour property to the device tree for sandbox. This uses platform data, a device tree node, driver private data and a remove() method.

| * tegra: Convert tegra GPIO driver to use driver modelSimon Glass2014-09-104-62/+283
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an implementation of GPIOs for Tegra that uses driver model. It has been tested on trimslice and also using the new iotrace feature. The implementation uses a top-level GPIO device (which has no actual GPIOS). Under this all the banks are created as separate GPIO devices. The GPIOs are named as per the Tegra datasheet/header files: A0..A7, B0..B7, ..., Z0..Z7, AA0..AA7, etc. Since driver model is not yet available before relocation, or in SPL, a special function is provided for seaboard's SPL code.

| * dm: Make driver model available before board_init()Simon Glass2014-09-103-16/+50
| | | | | | | | | | | | | | | | | | | | | | For some boards board_init() will change GPIOs, so we need to have driver model available before then. Adjust the board init to arrange this, but enable it for driver model only, just to be safe. This does create additional #ifdef logic, but it is safer than trying to make a pervasive change which may cause some boards to break. Signed-off-by: Simon Glass <sjg@chromium.org>
| * Set up stdio earlier when using driver modelSimon Glass2014-09-101-6/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | Since driver model registers itself with the stdio subsystem, and we want to avoid delayed registration and other complexity associated with the current serial console, move the stdio subsystem init earlier when driver model is used for serial. This simplifies the implementation. Should there be any problems with this approach they can be dealt with as boards are converted over to use driver model for serial.

| * dm: Move pre-reloc init earlier to cope with board_early_init_f()Simon Glass2014-09-101-2/+2
| | | | | | | | | | | | | | | | | | In order to support GPIO access in board_early_init_f() we must set up driver model before this function is called. In any case, earlier is better since driver model is (or will become) a key function for most init. Signed-off-by: Simon Glass <sjg@chromium.org>

| * arm: Fix _start for CONFIG_SYS_DV_NOR_BOOT_CFGBenoît Thébaudeau2014-09-111-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The boards using CONFIG_SYS_DV_NOR_BOOT_CFG (i.e. calimain, da850evm_direct_nor and enbw_cmc) had the _start symbol defined after the CONFIG_SYS_DV_NOR_BOOT_CFG word rather than before it in arch/arm/lib/vectors.S. Because of that, if by lack of luck 'gd->mon_len = (ulong)&__bss_end - (ulong)_start' (see setup_mon_len()) was a multiple of 4 kiB (see reserve_uboot()), then the last BSS word overlapped the first word of the following reserved RAM area (or went beyond the top of RAM without such an area) after relocation because __image_copy_start did not match _start (see relocate_code()). This was broken by commit 41623c9 'arm: move exception handling out of start.S files', which defined _start twice (before and after the CONFIG_SYS_DV_NOR_BOOT_CFG word), then by commit 0a26e1d 'arm: fix a double-definition error of _start symbol', which kept the definition of the _start symbol after the CONFIG_SYS_DV_NOR_BOOT_CFG word. This new commit fixes this issue by restoring the original behavior, i.e. by defining the _start symbol before the CONFIG_SYS_DV_NOR_BOOT_CFG word.

| * arm: Make reset position-independentBenoît Thébaudeau2014-09-111-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some boards, like mx31pdk and tx25, require the beginning of the SPL code to be position-independent. For these two boards, this is because they use the i.MX external NAND boot, which starts by executing the first NAND Flash page from the NFC page buffer. The SPL then needs to copy itself to its actual link address in order to free the NFC page buffer and use it to load the non-SPL image from Flash before running it. This means that the SPL runtime address differs from its link address between the reset and the initial copy performed by board_init_f(), so this part of the SPL binary must be position-independent. This requirement was broken by commit 41623c9 'arm: move exception handling out of start.S files', which used an absolute address to branch to the reset routine. This new commit restores the original behavior, which just performed a relative branch. This fixes the boot of mx31pdk and tx25.
