global_data: Ensure we have when symbols are not in Kconfig yet

2021-06-23T12:45:03Z

All symbols that are defined in Kconfig will always be defined (or not) prior to preprocessing due to the -include directive while building. However, symbols which are not yet migrated will only be defined (or not) once the board config.h is included, via . While the end goal must be to migrate all symbols, today we have cases where the size of gd will get mismatched within the build, based on include order. Mitigate this by making sure that any that uses symbols not in Kconfig does start with . Remove this when not needed.

reset: Remove addr parameter from reset_cpu()

2021-03-02T19:03:02Z

Historically, the reset_cpu() function had an `addr` parameter which was meant to pass in an address of the reset vector location, where the CPU should reset to. This feature is no longer used anywhere in U-Boot as all reset_cpu() implementations now ignore the passed value. Generic code has been added which always calls reset_cpu() with `0` which means this feature can no longer be used easily anyway. Over time, many implementations seem to have "misunderstood" the existence of this parameter as a way to customize/parameterize the reset (e.g. COLD vs WARM resets). As this is not properly supported, the code will almost always not do what it is intended to (because all call-sites just call reset_cpu() with 0). To avoid confusion and to clean up the codebase from unused left-overs of the past, remove the `addr` parameter entirely. Code which intends to support different kinds of resets should be rewritten as a sysreset driver instead. This transformation was done with the following coccinelle patch: @@ expression argvalue; @@ - reset_cpu(argvalue) + reset_cpu() @@ identifier argname; type argtype; @@ - reset_cpu(argtype argname) + reset_cpu(void) { ... } Signed-off-by: Harald Seiler Reviewed-by: Simon Glass

common: Drop asm/global_data.h from common header

2021-02-02T20:33:42Z

Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include at all, so remove that include. Signed-off-by: Simon Glass Signed-off-by: Tom Rini

arc: m68k: nds32: nios2: sh: xtensa: Add empty spl.h header

2021-01-05T19:24:40Z

At present it is not possible to include spl.h in on these architectures since the asm/spl.h file is not present. We want to be able to use the spl_phase() function, so add empty headers to make things build. Signed-off-by: Simon Glass

spi: dw: Add SoC-specific compatible strings

2020-12-18T10:46:37Z

This adds SoC-specific compatible strings to all users of the designware spi device. This will allow for the correct driver to be selected for each device. Where it is publicly documented, a compatible string for the specific device version has also been added. Devices without publicly-documented device versions include MSCC SoCs, and Arc Socs. All compatible strings except those for SoCFPGAs and some of the versioned strings have been taken from Linux. Since SSI_MAX_XFER_SIZE is determined at runtime, this is not strictly necessary. However, it is a good cleanup and brings things closer to Linux. Signed-off-by: Sean Anderson Tested-by Eugeniy Paltsev Reviewed-by: Jagan Teki

board_f: Factor out bdinfo bi_mem{start, size} to setup_bdinfo

2020-08-06T18:26:35Z

Move all assignments to gd->bd->bi_mem{start,size} to generic code in setup_bdinfo. Xtensa architecture is special in this regard as it defines its own handling of gd->bd->bi_mem{start,size} fields. In order to avoid defining a weak SDRAM function, let arch_setup_bdinfo overwrite the generic flags. For ARC architecture, remove ARCH_EARLY_INIT_R from Kconfig since it is not needed anymore. Also, use gd->ram_base to populate bi_memstart to avoid an ifdef. Signed-off-by: Ovidiu Panait Acked-by: Alexey Brodkin Reviewed-by: Simon Glass
