2016-04-01usb: Rename ehci-fsl.h to ehci-ci.hMateusz Kulikowski
Most of ehci-fsl header describe USB controller designed by Chipidea and used by various SoC vendors. This patch renames it to a generic header: ehci-ci.h Contents of file are not changed (so it contains several references to freescale SoCs).

2014-10-29kconfig: arm: introduce symbol for ARM CPUsGeorges Savoundararadj
This commit introduces a Kconfig symbol for each ARM CPU: CPU_ARM720T, CPU_ARM920T, CPU_ARM926EJS, CPU_ARM946ES, CPU_ARM1136, CPU_ARM1176, CPU_V7, CPU_PXA, CPU_SA1100. Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected for CPU_ARM1176 and CPU_V7. For each target, the corresponding CPU is selected and the definition of SYS_CPU in the corresponding Kconfig file is removed. Also, it removes redundant "string" type in some Kconfig files.

2014-09-13kconfig: remove redundant "string" type in arch and board KconfigsMasahiro Yamada
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>
2014-07-30Add board MAINTAINERS filesMasahiro Yamada
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.

2014-07-30kconfig: add board Kconfig and defconfig filesMasahiro Yamada
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/.

2013-11-27mx51evk: Fix pmic_init() argumentFabio Estevam

2012-11-14pmic: Extend PMIC framework to support multiple instances of PMIC devicesŁukasz Majewski
The PMIC framework has been extended to support multiple instances of the variety of devices responsible for power management. This change allows supporting of e.g. fuel gauge, charger, MUIC (Micro USB Interface Circuit). Power related includes have been moved to ./include/power directory. This is a first of a series of patches - in the future "pmic" will be replaced with "power". Two important issues: 1. The PMIC needs to be initialized just after malloc is configured 2. It uses list to hold information about available PMIC devices Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Cc: Stefano Babic <sbabic@denx.de>

On mxc, each SDHC instance has a dedicated clock, so gd->sdhc_clk is not suitable for the multi-instance use case (initialization made directly with fsl_esdhc_initialize()).

2012-09-23mx51evk: Add CONFIG_REVISION_TAGBenoît Thébaudeau
FSL 2.6.35 kernel assumes that the bootloader passes the CONFIG_REVISION_TAG information. If this data is not present, the kernel misconfigures the TZIC, which results in the timer interrupt handler never being called, so the kernel deadlocks while calibrating its delay.

2012-09-01fsl_esdhc: Remove cache snooping for i.MXBenoît Thébaudeau
The cache snooping feature of Freescale's eSDHC IP is not available on i.MX, so disable it globally for this architecture. This avoids setting no_snoop for all i.MX boards, and it prevents setting a reserved bit of a reserved register if fsl_esdhc_mmc_init() is used on i.MX, like in arch/arm/cpu/armv7/imx-common/cpu.c/cpu_mmc_init(). Since no_snoop was only used on i.MX, get rid of it BTW.

2012-01-08mmc: Change board_mmc_getcd() function prototype.Thierry Reding
The new API no longer uses the extra cd parameter that was used to store the card presence state. Instead, this information is returned via the function's return value. board_mmc_getcd() returns -1 to indicate that no card-detection mechanism is implemented; 0 indicates that no card is present and 1 is returned if it was detected that a card is present. The rationale for this change can be found in the following email thread: http://lists.denx.de/pipermail/u-boot/2011-November/110180.html In summary, the old API was not consistent with the rest of the MMC API which always passes a struct mmc as the first parameter. Furthermore the cd parameter was used to mean "card absence" in some implementations and "card presence" in others.

2010-11-17Switch from archive libraries to partial linkingSebastien Carlier
Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>

2010-10-28mx51evk: Fix 2 hours reset issueShawn Guo
The mx51evk u-boot has an issue that system will get reset every 2 hours. MC13892 has an inside charge timer which expires in 120 minutes. If ICHRG and CHGAUTOB are not set properly, this timer expiration will get system power recycled. Since mx51evk has no Li-Ion battery on board, the patch sets ICHRG in externally powered mode and sets CHGAUTOB bit to avoid automatic charging, so that system will not get reset by this timer expiration. The patch also corrects the bit field definition of register 48 (Charger 0) per latest MC13892 Reference Manual. Signed-off-by: Shawn Guo <shawn.gsc@gmail.com>
