* ARM: OMAP3: rx51: Enable workaround for ARM errata 454179, 430973, 621766Nishanth Menon2015-03-13-7/+12
| | | | | | | | | | | | RX51 has a secure logic which uses different parameters compared to traditional implementation. So, make the generic secure acr write over-ride-able by board file and refactor rx51 code to use this. While at it, enable the OMAP3 specific errata code for 454179, 430973, 621766.

* arm: Allow lr to be saved by board codeSimon Glass2015-02-16-1/+2
| | | | | | | | | | | | | | | The link register value can be required on some boards (e.g. FEL mode on sunxi) so use a branch instruction to jump to save_boot_params() instead of a branch link. This requires a branch back to save_boot_params_ret so adjust the users to deal with this. For exynos just drop the function since it doesn't do anything.

* Nokia RX-51: Do not call secure PPA routine on non secure devicesPali Rohár2015-01-12-1/+5
| | | | | | | | | | | | | Since commit 41623c91b09a0c865fab41acdaff30f060f29ad6 u-boot running in qemu is crashing in function do_omap3_emu_romcode_call(). RX-51 board uses this function for Cortex-A8 errata 430973 workaround (Set IBE bit in ACR) which is needed only on real secure device and not in qemu. This board patch just disable calling secure PPA routine on non secure devices. Qemu implements GP device and with this patch u-boot is working in qemu again.

* omap_hsmmc: Board-specific TWL4030 MMC power initializationsPaul Kocialkowski2014-12-04-0/+6
| | | | | | | | | | | | Boards using the TWL4030 regulator may not all use the LDOs the same way (e.g. MMC2 power can be controlled by another LDO than VMMC2). This delegates TWL4030 MMC power initializations to board-specific functions, that may still call twl4030_power_mmc_init for the default behavior.

* kconfig: remove redundant "string" type in arch and board KconfigsMasahiro Yamada2014-09-13-3/+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>

* Add board MAINTAINERS filesMasahiro Yamada2014-07-30-0/+6
| | | | | | | | | | | | | | | | | | | | We have switched to Kconfig and the boards.cfg file is going to be removed. We have to retrieve the board status and maintainers information from it. The MAINTAINERS format as in Linux Kernel would be nice because we can crib the scripts/get_maintainer.pl script. After some discussion, we chose to put a MAINTAINERS file under each board directory, not the top-level one because we want to collect relevant information for a board into a single place. TODO: Modify get_maintainer.pl to scan multiple MAINTAINERS files.

* kconfig: add board Kconfig and defconfig filesMasahiro Yamada2014-07-30-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds: - arch/${ARCH}/Kconfig provide a menu to select target boards - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig set CONFIG macros to the appropriate values for each board - configs/${TARGET_BOARD}_defconfig default setting of each board (This commit was automatically generated by a conversion script based on boards.cfg) In Linux Kernel, defconfig files are located under arch/${ARCH}/configs/ directory. It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.

* stdio: Pass device pointer to stdio methodsSimon Glass2014-07-23-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | At present stdio device functions do not get any clue as to which stdio device is being acted on. Some implementations go to great lengths to work around this, such as defining a whole separate set of functions for each possible device. For driver model we need to associate a stdio_dev with a device. It doesn't seem possible to continue with this work-around approach. Instead, add a stdio_dev pointer to each of the stdio member functions. Note: The serial drivers have the same problem, but it is not strictly necessary to fix that to get driver model running. Also, if we convert serial over to driver model the problem will go away. Code size increases by 244 bytes for Thumb2 and 428 for PowerPC. 22: stdio: Pass device pointer to stdio methods arm: (for 2/2 boards) all +244.0 bss -4.0 text +248.0 powerpc: (for 1/1 boards) all +428.0 text +428.0 Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Marek Vasut <marex@denx.de> Reviewed-by: Marek Vasut <marex@denx.de>
