2020-02-28ARM: uniphier: detect the base of micro support card at run-timeMasahiro Yamada
The base address 0x43f00000 is no longer true for the future SoC. Extract the base address from the device tree. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2020-02-28ARM: uniphier: remove workaround for the NAND write protectMasahiro Yamada
This workaround was previously needed for LD4, Pro4, sLD8, Pro5 SoCs. The boot ROM does not touch this register for PXs2/LD6b or later. Now that the reset signal of the Denali NAND controller is always asserted in board_init() then deasserted in the driver, the WRITE_PROTECT register gets back to the default value, which means the write protect is deasserted. This workaround can go away entirely. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2020-02-28ARM: uniphier: move NAND reset assertion to U-Boot proper from SPLMasahiro Yamada
The comment /* deassert reset */ is wrong. It asserts the reset. It no longer needs to stay in SPL. The NAND controller reset is handled in the driver. So, this assert can be moved to the board_init() of U-Boot proper. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2020-02-28ARM: uniphier: add sdscript, sdboot, sdupdate environment variablesMasahiro Yamada
Add handy macros: - sdscript: source boot.scr in the file system of the SD media - sdboot : boot the kernel using the images in the file system of the SD media - sdscript: update the boot firmware in the SD media (in raw block sectors) Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2020-01-17common: Move hang() to the same header as panic()Simon Glass

2019-12-02common: Move some cache and MMU functions out of common.hSimon Glass
These functions belong in cpu_func.h. Another option would be cache.h but that code uses driver model and we have not moved these cache functions to use driver model. Since they are CPU-related it seems reasonable to put them here. Move them over. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>

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 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.

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'.

2018-05-07arm: 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.
