2019-07-10ARM: uniphier: set {kernel, ramdisk, fdt}_addr_r at boot-timeMasahiro Yamada
The base of DRAM will be changed for the next generation SoC. The addresses needed for booting the kernel should be shifted according to the DRAM base. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2019-07-10ARM: uniphier: set dram_base environment variableMasahiro Yamada
The base of DRAM will be changed for the next generation SoC. Set the base address to the 'dram_base' environment variable, which will be useful for scripting. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2019-07-10ARM: uniphier: set loadaddr at boot-timeMasahiro Yamada
The base of DRAM will be changed for the next generation SoC. To support it along with existing SoCs in the single defconfig, set 'loadaddr' at boot-time by adding the offset to the DRAM base. CONFIG_SYS_LOAD_ADDR is still hard-coded for compilation, but the value from environment variable 'loadaddr' should be used. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2019-07-10ARM: uniphier: remove CONFIG_SYS_SDRAM_BASEMasahiro Yamada
The base address of DRAM was 0x80000000 for all the ARM SoCs of this family in the past. It will be changed to 0x20000000 for a planned new SoC. To support multiple SoCs by the single uniphier_v8_defconfig, the base must be run-time determined. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2019-07-10ARM: uniphier: make mem_map run-time configurableMasahiro Yamada
Currently, mem_map is hard-coded, and it worked well until the last SoC. For a planned new SoC, the addresses of peripherals and DRAM will be changed. Set it up run-time. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2019-07-10ARM: uniphier: make dram_init() independent of SG_MEMCONFMasahiro Yamada
Currently, dram_init() code relies on the fact the DRAM size configuration exists in the SG_MEMCONF register. This will no longer be true for a planned new SoC, which will replace SG_MEMCONF with a different register. Refactor the hook in a more generic way. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2019-07-10ARM: uniphier: detect register base addresses run-timeMasahiro Yamada
Until the last SoC, the register addresses have been hard-coded because they are always constant. For a planned new SoC, the register bases will be completely changed. I insist on supporting multiple SoCs/boards by a single defconfig (uniphier_v8_defconfig) since duplicating similar defconfig files is a maintenance burden. The base addresses must be fixed-up at run-time somehow. Previously, the board init code identified the SoC by reading out the SG_REVISION register. This is much easier than parsing DT. You cannot do it any more because the base address of SG will be changed. The SG_REVISION register exists to read out the SoC ID, but you never know its address before identifying the SoC. Oh well. So, the possible solution is to parse the DT, and find out the node with "*-soc-glue" compatible string. Then, sg_base is set to the value of the "reg" property. The sc_base is set up likewise. It is worth noting a pit-fall. Having sc_base and sg_base in the global scope will make the life easier, but the global variables are poorly supported before the relocation. In fact, the .bss section overwraps with DT. Allocating them in the .bss section would break DT. So, I gave dummy initializers to assign them in the .data section.

2019-07-10ARM: uniphier: de-couple SC macros into base address and offsetMasahiro Yamada

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: 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.

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'.

2018-07-25ARM: 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.
