* Move default y configs out of arch/board KconfigJoe Hershberger2015-06-25-3/+0
| | | | | | | | | | | | | | | | | | | Some archs/boards specify their own default by pre-defining the config which causes the Kconfig system to mix up the order of the configs in the defconfigs... This will cause merge pain if allowed to proliferate. Remove the configs that behave this way from the archs. A few configs still remain, but that is because they only exist as defaults and do not have a proper Kconfig entry. Those appear to be: SPIFLASH DISPLAY_BOARDINFO Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> [trini: rastaban, am43xx_evm_usbhost_boot, am43xx_evm_ethboot updates, drop DM_USB from MSI_Primo81 as USB_MUSB_SUNXI isn't converted yet to DM] Signed-off-by: Tom Rini <trini@konsulko.com>
* arch: Make board selection choices optionalJoe Hershberger2015-05-12-0/+1
| | | | | | | | | | | | By making the board selections optional, every defconfig will include the board selection when running savedefconfig so if a new board is added to the top of the list of choices the former top's defconfig will still be correct.

* MIPS: implement device-tree handover to Linux kernelDaniel Schwierzeck2015-04-24-6/+3
| | | | | | | | | | | Add device-tree handover to Linux kernel conforming with MIPS UHI [1]. Register $a0 will be set to the reserved value -2. The address of the device-tree blob will be stored as KSEG0 address in $a1. $a2 and $a3 are set to zero.

* MIPS: allow systems to skip loads during cache initPaul Burton2015-01-29-0/+6
| | | | | | | | | | | | | Current MIPS systems do not require that loads be performed to force the parity of cache lines, a simple invalidate by clearing the tag for each line will suffice. Thus this patch makes the loads & subsequent second invalidation conditional upon the CONFIG_SYS_MIPS_CACHE_INIT_RAM_LOAD option, and defines that for existing mips32 targets. Exceptions are malta where this is known to be unnecessary, and qemu-mips where caches are not implemented.

* MIPS: replace $(CPU) with Kconfig symbolsDaniel Schwierzeck2015-01-21-0/+8
| | | | | | | Conditionally set head-y and lib-y with boolean Kconfig symbols for selected CPU. This deprecates the usage of the $(CPU) variable. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
* MIPS: bootm: prepare a flattened device tree for the kernelDaniel Schwierzeck2015-01-21-0/+11
| | | | | | | | | | | | Add the initial code to prepare a flattened device tree for the kernel like relocating the FDT blob and fixing up the /chosen and /memory nodes. The final hand over to the kernel is not yet implemented. After the community agreed on the MIPS boot interface for device trees, the corresponding code will be added.

* MIPS: bootm: refactor preparation of Linux kernel environmentDaniel Schwierzeck2015-01-21-0/+9
| | | | | | | | Move preparation of Linux kernel environment in a separate function and mark it as legacy. Add a Kconfig option to make that legacy mode configurable. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>

* MIPS: kconfig: merge targets qemu_mips and qemu_mips64Daniel Schwierzeck2014-11-01-6/+2
| | | | | | | | Now the user can separately select the CPU type. Thus the targets qemu_mips and qemu_mips64 can be merged to a single target. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
* MIPS: kconfig: globally define CONFIG_SYS_CPU for MIPSDaniel Schwierzeck2014-11-01-0/+4
| | | | | | | Now the user can select the CPU type for each target. Thus CONFIG_SYS_CPU could be set globally. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
* MIPS: kconfig: add options for CPU type selectDaniel Schwierzeck2014-11-01-0/+68
| | | | | | | | Add new Kconfig option to let the user select the targets CPU type. Each target have to select SUPPORTS_CPU_MIPS[32,64]_R[1,2] to indicate which CPU types are supported. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>

* mips: enable CONFIG_USE_PRIVATE_LIBGCC by defaultMasahiro Yamada2014-10-23-0/+3
| | | | | | | | | | | | | | | | | | Without the private libgcc, we need a full multilib toolchain with different libgcc or multiple toolchains to build all BE/LE and hard-float/soft-float variants of MIPS boards. That is not feasible. This commit allows us to build all the MIPS boards with a single kernel.org toolchain: https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.9.0/ x86_64-gcc-4.9.0-nolibc_mips-linux.tar.xz This change sounds reasonable for most users. If necessary, you can disable this option via "make menuconfig" or friends. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
* kconfig: remove redundant "string" type in arch and board KconfigsMasahiro Yamada2014-09-13-1/+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 board Kconfig and defconfig filesMasahiro Yamada2014-07-30-0/+37
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/.
