2019-07-10ARM: uniphier: make boot_is_swapped() code optionalMasahiro Yamada
The planned new SoC does not have SBC (System Bus Controller) block. Make boot_is_swapped() an optional hook. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2019-07-10ARM: uniphier: check DT to determine whether to initialize SBCMasahiro Yamada
If CONFIG_MICRO_SUPPORT_CARD is enabled, U-Boot initialize SBC (System Bus Controller), which may not be really necessary. Check the "socionext,uniphier-system-bus" node in DT run-time. If and only if it is found and its "status" property is okay, initialize the SBC block. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2019-07-10ARM: uniphier: check DT to determine whether to use support cardMasahiro Yamada
If CONFIG_MICRO_SUPPORT_CARD is enabled, U-Boot tries to get access to the devices on the support card, which may not actually exist. Check the DT and search for the on-board devices run-time. If the nodes are not found in DT, then disable the code. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2019-06-29ARM: uniphier: move sg_set_{pinsel, iectrl} to more relevant placesMasahiro Yamada
Move the sg_set_pinsel macro to arch/arm/mach-uniphier/arm32/debug_ll.S since it is not used anywhere else. Move the C functions sg_set_{pinsel,iectrl} to debug-uart.c since they are not used anywhere else. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2019-06-29ARM: uniphier: remove unused init code for CONFIG_DEBUG_UARTMasahiro Yamada
debug_uart_init() is called from spl_board_init(), which is only compiled for SPL. For U-boot proper, _debug_uart_init() is unreachable, so dropped by the dead code elimination. Now that 64-bit SoCs of this SoC family no longer support SPL, debug-uart-ld20.c is never compiled. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2018-12-29ARM: uniphier: do not modify bootcmd environment variable at run-timeMasahiro Yamada
Some users might want to modify 'bootcmd' at compile-time by editing include/configs/uniphier.h, but overwriting it at run-time makes it impossible. Instead, set 'bootdev' at run-time, which contains the boot device the system is booting from, then indirectly reference it from 'bootcmd'. It is up to users whether to override 'bootcmd'.

2018-09-20mtd: move NAND files into a raw/ subdirectoryMiquel Raynal
NAND flavors, like serial and parallel, have a lot in common and would benefit to share code. Let's move raw (parallel) NAND specific code in a raw/ subdirectory, to ease the addition of a core file in nand/ and the introduction of a spi/ subdirectory specific to SPI NANDs.

2018-07-25ARM: uniphier: enable distro bootMasahiro Yamada
Switch to the distro boot for UniPhier platform. - Remove the environment vairalbes used to load images from raw block devices. - Keep the command to download images via tftp. This will be useful to boot the kernel when no valid kernel image is ready yet in the file system. - Use root.cpio.gz instead of root.cpio.uboot because we always know the file size of the init ramdisk; it is loaded via either a file system or network. - Rename fit_addr_r to kernel_addr_r, which the distro command checks to get the load address of FIT image.

2018-05-07arm: v7: Kconfig: Rename CPU_V7 as CPU_V7ALokesh Vutla
Currently CPU_V7 kconfig symbol supports only ARMv7A architectures under armv7 folder. This led to a misconception of creating separate folders for armv7m and armv7r. There is no reason to create separate folder for other armv7 based architectures when it can co-exist with few Kconfig symbols. As a first step towards a common folder, rename CPU_V7 as CPUV7A. Later separate Kconfig symbols can be added for CPU_V7R and CPU_V7M and can co exist in the same folder.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2018-01-09ARM: uniphier: do not use RAM that exceeds 32 bit address rangeMasahiro Yamada
LD20 / PXs3 boards are equipped with a large amount of memory beyond the 32 bit address range. U-Boot relocates itself to the end of the available RAM. This is a problem for DMA engines that only support 32 bit physical address, like the SDMA of SDHCI controllers. In fact, U-Boot does not need to run at the very end of RAM. It is rather troublesome for drivers with DMA engines because U-Boot does not have API like dma_set_mask(), so DMA silently fails, making the driver debugging difficult. Hide the memory region that exceeds the 32 bit address range. It can be done by simply carving out gd->ram_size. It would also possible to override get_effective_memsize() or to define CONFIG_MAX_MEM_MAPPED, but dram_init() is a good enough place to do this job.

UniPhier 32-bit SoCs use CONFIG_SPL_OF_CONTROL. So, many nodes must be marked as dm-pre-reloc to prevent fdtgrep from stripping them off. Sprinkling U-Boot-specific properties all over the place is painful because DT files are synced with Linux from time to time. Split u-boot,dm-pre-reloc out to uniphier-v7-u-boot.dtsi, which is appended to UniPhier V7 DTS before the build.

2017-10-04printk: collect printk stuff into <linux/printk.h> with loglevel supportMasahiro Yamada
When we import code from Linux, with regular re-sync planned, we want to use printk() and pr_*(). U-Boot does not support them in a clean way. So, people end up with local macros, or compat headers here and there, then we occasionally see build errors of definition conflicts. We have include/linux/compat.h, but putting all sorts of unrelated things into a single header is just a temporal workaround. Hence this patch, to find the best home for all printk variants. If you want to use printk() and friends, please include <linux/printk.h>. This header is self-contained, and pulls in only a few headers. When I was testing this clean-up, I noticed the image size exceeded its platform limit on some boards. This is because all pr_*() that were previously defined as no-op in include/linux/mtd/mtd.h (unless CONFIG_MTD_DEBUG is set), are now enabled. To make such boards happy, this commit also implements CONFIG_LOGLEVEL. The concept is similar to the kernel parameter "loglevel". (Actually, the Kconfig help message was taken from kernel-paremeter.txt of Linux) Messages with a loglevel smaller than console loglevel will be printed. The difference is the loglevel is build-time determined. To save the image size, lower priority pr_*() are compiled out. I set the default of CONFIG_LOGLEVEL to 6, i.e. pr_notice and higher priority messages are compiled in. I adjusted CONFIG_LOGLEVEL to avoid build error for some boards.
