* ARM: uniphier: adjust fdt_file environment handling to latest LinuxMasahiro Yamada2016-10-29-12/+9
| | | | | | | The environment fdt_file is useful to remember the appropriate DTB file name. Adjust it to the recent renaming in the upstream kernel. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* libfdt: Bring in upstream stringlist functionsSimon Glass2016-10-13-3/+2
| | | | | | | | | | | | | | These have now landed upstream. The naming is different and in one case the function signature has changed. Update the code to match. This applies the following upstream commits by Thierry Reding <treding@nvidia.com> : 604e61e fdt: Add functions to retrieve strings 8702bd1 fdt: Add a function to get the index of a string 2218387 fdt: Add a function to count strings Signed-off-by: Simon Glass <sjg@chromium.org>
* ARM: uniphier: do not overwrite fdt_file environmentMasahiro Yamada2016-06-09-0/+3
| | | | | | | | This code auto-detects the best-match FDT file name, but it should respect the user's choice if "fdt_file" environment is found in a saved set of environments. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: check return code of setenv()Masahiro Yamada2016-06-09-3/+1
| | | | | | Because setenv() may fail, it is better to check its return code. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: rework uniphier_set_fdt_file()Masahiro Yamada2016-04-24-31/+31
| | | | | | | | | | | | The current table look-up for the DTB file name turned out bothersome in terms of maintainability; I ended up adding a new entry every time a new board is supported. There is a common pattern between the DT compatible string and the corresponding file name; drop the vendor prefix "socionext," and prefix it with "uniphier-" and suffix it with ".dtb".

* ARM: uniphier: carry on booting for Unknown boot modeMasahiro Yamada2016-04-24-2/+2
| | | | | | | | No need to stop booting U-Boot even if boot mode is unknown. Setting the "bootmode" environment is only useful for booting Linux Kernel. Anyway, U-Boot has already booted by this point. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: add support for PH1-Pro4 Ace and Sanji boardsMasahiro Yamada2016-02-14-0/+2
| | | | | | | | | | Initial commit for PH1-Pro4 Ace and Sanji boards. Note: There are two variants for the Ace board in terms of the amount of DDR memory; 1GB or 2GB. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: support USB boot mode for ProXstream2 / PH1-LD6b SoCMasahiro Yamada2016-02-14-1/+7
| | | | | | | | | | | | | | | | | | The USB boot code is too fat and complicated to be included in SPL (at least for now). So, it was implemented as a separate project (what we call USB-loader). The expected boot sequence is as follows: Boot ROM -> USB-loader -> SPL -> U-Boot proper The USB-loader loads the SPL and U-Boot proper from a USB memory onto the locked L2 cache. Then, SPL needs to copy the U-Boot proper to DRAM, so this mode looks like a NOR boot from the view of SPL. However, we want to distinguish between (genuine) NOR boot and USB boot in some places.

* ARM: uniphier: set DTB file name to fdt_file environmentMasahiro Yamada2015-12-23-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | When we want to boot Linux with a DTB file downloaded from a TFTP server or somewhere, we need to know the file name to be downloaded. Assume the U-Boot configuration is shared among some similar boards. If they are similar enough, the difference only appears in device trees. The build procedure would be like this: - Board A: make foo_common_defconfig && make DEVICE_TREE=foo_board_a - Board B: make foo_common_defconfig && make DEVICE_TREE=foo_board_b - Board C: make foo_common_defconfig && make DEVICE_TREE=foo_board_c In this case, the U-Boot image contains nothing about the DTB file name it is running with. (CONFIG_DEFAULT_DEVICE_TREE is not helpful for this purpose because it is painful to change it from "make menuconfig" for each board.) This commit allows to lookup the DTB file name based on the compatible string and set it to "fdt_file" environment. Then "tftpboot $fdt_file" will download the file we want.

* ARM: UniPhier: replace <asm/io.h> with <linux/io.h>Masahiro Yamada2015-05-31-3/+2
| | | | | | | In the Linux coding style, it is recommended to include <linux/io.h> rather than <asm/io.h>. Follow this trend. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: UniPhier: move SoC sources to mach-uniphierMasahiro Yamada2015-03-01-0/+53
Move arch/arm/cpu/armv7/uniphier/* -> arch/arm/mach-uniphier/* Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
