* fdt: Allow ft_board_setup() to report failureSimon Glass2014-11-21-1/+3
| | | | | | | | | | | | | | | | | | This function can fail if the device tree runs out of space. Rather than silently booting with an incomplete device tree, allow the failure to be detected. Unfortunately this involves changing a lot of places in the code. I have not changed behvaiour to return an error where one is not currently returned, to avoid unexpected breakage. Eventually it would be nice to allow boards to register functions to be called to update the device tree. This would avoid all the many functions to do this. However it's not clear yet if this should be done using driver model or with a linker list. This work is left for later.

* MAINTAINERS: comment out blank M: fieldMasahiro Yamada2014-09-24-1/+1
| | | | | | | | | | | | | | | | | | Since commit ddaf5c8f3030050fcd356a1e49e3ee8f8f52c6d4 (patman: RunPipe() should not pipe stdout/stderr unless asked), Patman spits lots of "Invalid MAINTAINERS address: '-'" error messages for patches with global changes. It takes too long for Patman to process them. Anyway, "M: -" does not carry any important information. Rather, it is just like a place holder in case of assigning a new board maintainer. Let's comment out. This commit can be reproduced by the following command: find . -name MAINTAINERS | xargs sed -i -e '/^M:[[:blank:]]*-$/s/^/#/' Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* 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/+11
| | | | | | | | | | | | | | | | | | | | 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/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | 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/.

* powerpc/mpc85xx: Check return value of find_tlb_idxYork Sun2014-07-22-3/+9
| | | | | | | | | | find_tlb_idx() is called in board_early_init_r() on multiple boards. The return value is not checked before being used to disable a TLB. In normal case the return value wouldn't be -1. In case of a mis- configuration during porting to a new board, checking the return value may be helpful to reveal some user errors.

Default lane muxing map is as below: Lane G on bank1 routes to SGMII, controlled by bit 1 of the reg; Lane A on bank2 routes to AURORA, controlled by bit 0 of the reg; Lane C/D on bank2 routes to SATA0 and SATA1, controlled by bit 2 and bit 3 respectively. Default value of these bits for lane muxing is '1', we should set or clear these bits accoring to RCW.

* powerpc/85xx: don't display address map size (32-bit vs. 36-bit) during bootTimur Tabi2012-04-24-4/+0
| | | | | | | | | | | | | | | | Most 85xx boards can be built as a 32-bit or a 36-bit. Current code sometimes displays which of these is actually built, but it's inconsistent. This is especially problematic since the "default" build for a given 85xx board can be either one, so if you don't see a message, you can't always know which size is being used. Not only that, but each board includes code that displays the message, so there is duplication. The 'bdinfo' command has been updated to display this information, so we don't need to display it at boot time. The board-specific code is deleted.
