2020-07-11bus: uniphier-system-bus: add UniPhier System Bus driverMasahiro Yamada
Since commit 1517126fdac2 ("ARM: uniphier: select DM_ETH"), DM-based drivers/net/smc911x.c is compiled, but it is never probed because the parent node lacks the DM-based driver. I need a skeleton driver to populate child devices (but the next commit will move more hardware settings to the this driver). I put this to drivers/bus/uniphier-system-bus.c because this is the same path as the driver in Linux kernel. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2020-07-11ARM: uniphier: consolidate SoC select menuMasahiro Yamada
Currently, the supports for the following two ARMv7 SoC groups are exclusive, because the boot ROM loads the SPL to a different address: - LD4, sLD8 (SPL is loaded at 0x00040000) - Pro4, Pro5, PXs2, LD6b (SPL is loaded at 0x00100000) This limitation exists only when CONFIG_SPL=y. Instead of using crappy CONFIG options, checking SPL and SPL_TEXT_BASE is cleaner. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2020-07-11Revert "ARM: uniphier: add weird workaround code for LD20"Masahiro Yamada
This reverts commit 45f41c134baf5ff1bbf59d33027f6c79884fa4d9. This weird workaround was the best I came up with at that time to boot U-Boot from TF-A. I noticed U-Boot successfully boots on LD20 (i.e. CA72 CPU) by using the latest TF-A. Specifically, since the following TF-A commit, U-Boot runs at EL2 instead of EL1, and this issue went away as a side-effect. |commit f998a052fd94ea082833109f25b94ed5bfa24e8b |Author: Masahiro Yamada <yamada.masahiro@socionext.com> |Date: Thu Jul 25 10:57:38 2019 +0900 | | uniphier: run BL33 at EL2 | | All the SoCs in 64-bit UniPhier SoC family support EL2. | | Just hard-code MODE_EL2 instead of using el_implemented() helper. | | Change-Id: I7ab48002c5205bc8c013e1b46313b57d6c431db0 | Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> However, if I reverted that, this problem would come back, presumably because some EL1 code in U-Boot triggers this issue.

2020-05-18command: Remove the cmd_tbl_t typedefSimon Glass
We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them. Drop the typedef and rename the struct to remove the _s suffix which is now not useful. This requires quite a few header-file additions. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-05-15spl: Always define preloader_console_initSamuel Holland
A large number of boards call preloader_console_init unconditionally. Currently, they fail to build with CONFIG_SPL_SERIAL=n, because the function is undefined in that case. To fix the build, always define preloader_console_init, but make it no-op when CONFIG_SPL_SERIAL=n. For the few boards that did check for CONFIG_SPL_SERIAL before calling preloader_console_init, remove the checks, since the function can now be called unconditionally.

The function's name is misleading as one might think it is used generally to select the boot-mode when in reality it is only used by the MMC driver to find out in what way it should try reading U-Boot Proper from a device (either using a filesystem, a raw sector/partition, or an eMMC boot partition). Rename it to spl_mmc_boot_mode() to make it more obvious what this function is about.

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

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.
