* ARM: renesas: Rename ARCH_RMOBILE to ARCH_RENESASMarek Vasut2024-03-021-1/+1
| | | | | | | | | | | | | | | Rename ARCH_RMOBILE to ARCH_RENESAS because all the chips are made by Renesas, while only a subset of them is from the R-Mobile line. Use the following command to perform the rename: " $ git grep -l 'ARCH_RMOBILE' | xargs -I {} sed -i 's@ARCH_RMOBILE@ARCH_RENESAS@g' {} " Signed-off-by: Marek Vasut <marek.vasut+renesas@mailbox.org> Reviewed-by: Paul Barker <paul.barker.ct@bp.renesas.com>

* sunxi: add R528/T113-s3/D1(s) DRAM initialisation codeAndre Przywara2023-10-225-0/+1574
| | | | | | | | | | | | | | | | | | | | | | The Allwinner R528/T113-s/D1/D1s SoCs all share the same die, so use the same DRAM initialisation code. Make use of prior art here and lift some code from awboot[1], which carried init code based on earlier decompilation efforts, but with a GPL2 license tag. This code has been heavily reworked and cleaned up, to match previous DRAM routines for other SoCs, and also to be closer to U-Boot's coding style and support routines. The actual DRAM chip timing parameters are included in the main file, since they cover all DRAM types, and are protected by a new Kconfig CONFIG_SUNXI_DRAM_TYPE symbol, which allows the compiler to pick only the relevant settings, at build time. The relevant DRAM chips/board specific configuration parameters are delivered via Kconfig, so this code here should work for all supported SoCs and DRAM chips combinations.

* Kconfig: sunxi: prepare for using drivers/ram/sunxiAndre Przywara2023-10-222-1/+8
| | | | | | | | | | | | | | | | | | | At the moment all Allwinner DRAM initialisation routines are stored in arch/arm/mach-sunxi, even though those "drivers" are just a giant collection of writel's, without any architectural dependency. The R528/T113-s SoC (with ARM cores) and the D1/D1s Soc (with RISC-V cores) share the same die, so should share the same DRAM init routines as well. To prepare for this, add a new sunxi directory inside drivers/ram, and add some stub entries to prepare for the addition of the share DRAM code for those SoCs. The RISC-V D1(s) SoCs will probably use SPL_DM, so for that SoC this would be the right directory anyway. Signed-off-by: Andre Przywara <andre.przywara@arm.com>
* treewide: use dev_read_addr_*_ptr() where appropriateMatthias Schiffer2023-10-132-23/+20
| | | | | | | | | | | | | | | | | | | | | A follow-up to commit 842fb5de424e ("drivers: use devfdt_get_addr_size_index_ptr when cast to pointer") and commit 320a1938b6f7 ("drivers: use devfdt_get_addr_index_ptr when cast to pointer"). In addition to using the *_ptr variants of these functions where the address is cast to a pointer, this also changes devfdt_get_addr_*() to dev_read_addr_*() in a few places. Some variable and field types are changed from fdt_addr_t or phys_addr_t to void* where the cast was happening later. This patch fixes a number of compile warnings when building a 32bit U-Boot with CONFIG_PHYS_64BIT=y. In some places, it also fixes error handling where the return value of dev_read_addr() etc. was checked for NULL instead of FDT_ADDR_T_NONE.

| | | | | | | | | | | | | | | The fdt_addr_t and phys_addr_t size have been decoupled. A 32bit CPU can expect 64-bit data from the device tree parser, so convert regmap_init_mem_plat() input to handel both. The syscon class driver also makes use of the regmap_init_mem_plat() function, but has no way of knowing the format of the device-specific platform data. In case of odd reg structures other then that the syscon class driver assumes the regmap must be filled in the individual syscon driver before pre-probe.
