2018-03-05libfdt: move headers to <linux/libfdt.h> and <linux/libfdt_env.h>Masahiro Yamada
Thomas reported U-Boot failed to build host tools if libfdt-devel package is installed because tools include libfdt headers from /usr/include/ instead of using internal ones. This commit moves the header code: include/libfdt.h -> include/linux/libfdt.h include/libfdt_env.h -> include/linux/libfdt_env.h and replaces include directives: #include <libfdt.h> -> #include <linux/libfdt.h> #include <libfdt_env.h> -> #include <linux/libfdt_env.h> Reported-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2017-08-16env: Rename getenv/_f() to env_get()Simon Glass
We are now using an env_ prefix for environment functions. Rename these two functions for consistency. Also add function comments in common.h. Quite a few places use getenv() in a condition context, provoking a warning from checkpatch. These are fixed up in this patch also.

This allows us to use the same DRAM init function on all archs. Add a dummy function for arc, which does not use DRAM init here. Signed-off-by: Simon Glass <sjg@chromium.org> [trini: Dummy function on nios2] Signed-off-by: Tom Rini <trini@konsulko.com>
2017-04-05board_f: Drop return value from initdram()Simon Glass
At present we cannot use this function as an init sequence call without a wrapper, since it returns the RAM size. Adjust it to set the RAM size in global_data instead, and return 0 on success. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Stefan Roese <sr@denx.de>
2017-04-05board_f: Drop board_type parameter from initdram()Simon Glass
It looks like only cm5200 and tqm8xx use this feature, so we don't really need it in generic code. Drop it and have the users access gd->board_type directly. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Stefan Roese <sr@denx.de>
2016-09-27usb: fsl: Rename fdt_fixup_dr_usbSriram Dash

2014-11-21fdt: Allow ft_board_setup() to report failureSimon Glass
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.

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>
2014-09-08net: Merge asm/fsl_enet.h into fsl_mdio.hClaudiu Manoil
fsl_enet.h defines the mapping of the usual MII management registers, which are included in the MDIO register block common to Freescale ethernet controllers. So it shouldn't depend on the CPU architecture but it should be actually part of the arch independent fsl_mdio.h. To remove the arch dependency, merge the content of asm/fsl_enet.h into fsl_mdio.h. Some files (like fm_eth.h) were simply including fsl_enet.h only for phy.h. These were updated to include phy.h instead. Signed-off-by: Claudiu Manoil <claudiu.manoil@freescale.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/.

2011-10-15punt unused clean/distclean targetsMike Frysinger

2011-04-20fsl: Change fsl_phy_enet_if to phy_interface_tAndy Fleming
The fsl_phy_enet_if enum was, essentially, the phy_interface_t enum. This meant that drivers which used fsl_phy_enet_if to deal with PHY interfaces would have to convert between the two (or we would have to have them mirror each other, and deal with the ensuing maintenance headache). Instead, we switch all clients of fsl_phy_enet_if over to phy_interface_t, which should become the standard, anyway.

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>

2010-10-18Makefile: move all Power Architecture boards into boards.cfgWolfgang Denk
Clean up Makefile, and drop a lot of the config.mk files on the way. We now also automatically pick all boards that are listed in boards.cfg (and with all configurations), so we can drop the redundant entries from MAKEALL to avoid building these twice. Signed-off-by: Wolfgang Denk <wd@denx.de>
2010-10-18Rename TEXT_BASE into CONFIG_SYS_TEXT_BASEWolfgang Denk
The change is currently needed to be able to remove the board configuration scripting from the top level Makefile and replace it by a simple, table driven script. Moving this configuration setting into the "CONFIG_*" name space is also desirable because it is needed if we ever should move forward to a Kconfig driven configuration system.

2008-10-21mpc83xx: fix PCI scan hang on the standalone MPC837xE-MDS boardsAnton Vorontsov
The MPC837xE-MDS board's CPLD can auto-detect if the board is on the PIB, standalone or acting as a PCI agent. User's Guide says: - When the CPLD recognizes its location on the PIB it automatically configures RCW to the PCI Host. - If the CPLD fails to recognize its location then it is automatically configured as an Agent and the PCI is configured to an external arbiter. This sounds good. Though in the standalone setup the CPLD sets PCI_HOST flag (it's ok, we can't act as PCI agents since we receive CLKIN, not PCICLK), but the CPLD doesn't set the ARBITER_ENABLE flag, and without any arbiter bad things will happen (here the board hangs during any config space reads). In this situation we must disable the PCI. And in case of anybody really want to use an external arbiter, we provide "pci_external_aribter" environment variable.

2008-10-21mpc83xx: fix serdes setup for the MPC8378E boardsAnton Vorontsov
MPC837xE specs says that SerDes1 has: — Two lanes running x1 SGMII at 1.25 Gbps; — Two lanes running x1 SATA at 1.5 or 3.0 Gbps. And for SerDes2: — Two lanes running x1 PCI Express at 2.5 Gbps; — One lane running x2 PCI Express at 2.5 Gbps; — Two lanes running x1 SATA at 1.5 or 3.0 Gbps. The spec also explicitly states that PEX options are not valid for the SD1. Nevertheless MPC8378 RDB and MDS boards configure the SD1 for PEX, which is wrong to do.

2008-06-12Change initdram() return type to phys_size_tBecky Bruce
This patch changes the return type of initdram() from long int to phys_size_t. This is required for a couple of reasons: long int limits the amount of dram to 2GB, and u-boot in general is moving over to phys_size_t to represent the size of physical memory. phys_size_t is defined as an unsigned long on almost all current platforms. This patch *only* changes the return type of the initdram function (in include/common.h, as well as in each board's implementation of initdram). It does not actually modify the code inside the function on any of the platforms; platforms which wish to support more than 2GB of DRAM will need to modify their initdram() function code.
