2025-03-29ram: renesas: dbsc5: Pass udevice and MODEMR0 to dbsc5_get_board_data()Marek Vasut
Pass DBSC5 udevice and MODEMR0 register values to board specific function dbsc5_get_board_data(). The board specific implementation of dbsc5_get_board_data() can return struct renesas_dbsc5_board_config which matches the board based on the content of MODEMR0 or content of DT accessible via the udevice.

2025-03-29ram: renesas: dbsc5: Improve dbsc5_send_dbcmd2() signatureMarek Vasut
Update dbsc5_send_dbcmd2() such that it takes multiple parameters instead of one magic register content value. These parameters are used to form the same resulting register value internally in the dbsc5_send_dbcmd2() function, but from well defined input constants. The new input constants are the operation code, channel, rank, and operation argument. The argument is operation code specific, therefore it is still a 16-bit magic number, but the rest of the arguments are now split up. No functional change.

2025-01-14ram: k3-ddrss: Use the DDR controller BIST engine for ECC primingGeorgi Vlaev
The 1-bit inline ECC support in TI's DDRSS bridge requires the configured memory regions to be preloaded with a pattern before use. This is done by the k3-ddrss driver from the R5 SPL in a 'for' loop. It takes around 10 seconds to fill 2GB of memory, for example. Memset can cut the time in half and using DMA currently yields a similar result. The BIST engine of DDR controller provides support for initializing any memory region with a pattern. This bypasses the DDRSS bridge, so the required inline ECC data is not computed and populated in the memory. For some values like zero, the computed ECC syndrome is also zero and we can use these values to preload the memory from the DDR controller, without the assistance of the bridge. The registers involved in the process are described in the 'DDR controller registers' topic in [1] AM62 and [2] J721E reference manuals. The patch replaces the 'for' loop memory fill function with the BIST memory initialization procedure. This cuts the time to preload the 2GB memory from 10 seconds down to 1 second. The bist preload function uses the lpddr4 APIs in the k3-ddrss, so this is compatible with devices with both 16-bit LPDDR4 and 32-bit LPDDR4 interfaces (e.g J721E).

2024-12-06ram: k3-ddrss: drop debug() in timing-sensitive sequenceThéo Lebrun
Those debug() calls might be useful, but beware. They can cause the DDR controller to hang if we do not run the sequence quickly enough. They usually are not an issue with upstream U-Boot and the default DDR config, but they have become troublesome with custom DDR configs. Drop those debug() statements that shouldn't be present in time-sensitive code, to avoid anyone else falling into the trap. Signed-off-by: Théo Lebrun <[email protected]>
2024-10-11Merge patch series "Tidy up use of 'SPL' and CONFIG_SPL_BUILD"Tom Rini
Simon Glass <[email protected]> says: When the SPL build-phase was first created it was designed to solve a particular problem (the need to init SDRAM so that U-Boot proper could be loaded). It has since expanded to become an important part of U-Boot, with three phases now present: TPL, VPL and SPL Due to this history, the term 'SPL' is used to mean both a particular phase (the one before U-Boot proper) and all the non-proper phases. This has become confusing. For a similar reason CONFIG_SPL_BUILD is set to 'y' for all 'SPL' phases, not just SPL. So code which can only be compiled for actual SPL, for example, must use something like this: #if defined(CONFIG_SPL_BUILD) && !defined(CONFIG_TPL_BUILD) In Makefiles we have similar issues. SPL_ has been used as a variable which expands to either SPL_ or nothing, to chose between options like CONFIG_BLK and CONFIG_SPL_BLK. When TPL appeared, a new SPL_TPL variable was created which expanded to 'SPL_', 'TPL_' or nothing. Later it was updated to support 'VPL_' as well. This series starts a change in terminology and usage to resolve the above issues: - The word 'xPL' is used instead of 'SPL' to mean a non-proper build - A new CONFIG_XPL_BUILD define indicates that the current build is an 'xPL' build - The existing CONFIG_SPL_BUILD is changed to mean SPL; it is not now defined for TPL and VPL phases - The existing SPL_ Makefile variable is renamed to SPL_ - The existing SPL_TPL Makefile variable is renamed to PHASE_ It should be noted that xpl_phase() can generally be used instead of the above CONFIGs without a code-space or run-time penalty. This series does not attempt to convert all of U-Boot to use this new terminology but it makes a start. In particular, renaming spl.h and common/spl seems like a bridge too far at this point. The series is fully bisectable. It has also been checked to ensure there are no code-size changes on any commit.

2024-03-13rockchip: migrate hardware.h inclusion into appropriate filesQuentin Schulz
hardware.h is only defining macros which are "wrappers" around writel(). writel() is however not available in hardware.h, <asm/io.h> needs to be included. This means in order to use the wrappers in hardware.h, one also needs to include the <asm/io.h> header. However, this cannot be done currently because hardware.h is included in include/configs files, which are implicitly included by every code file by default, which makes the compilation of arch/arm/cpu/armv8/u-boot.lds fail because ALIGN (the ARM assembly directive) got redefined by some of the include files coming from <asm.io.h>. Because nothing in the include/configs file actually use hardware.h, let's remove the inclusion of hardware.h from the include/configs files and explicitly add it wherever it is required.

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.

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 <[email protected]>
2023-10-13treewide: use dev_read_addr_*_ptr() where appropriateMatthias Schiffer
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.
