2021-09-21ARM: mach-at91: armv7: fix multiple cpu_reset definition when enabling SYSRESETClément Léger1-1/+3
When SYSRESET is enabled, cpu_reset function is also defined in sysreset-uclass.c which lead to multiple definitions of this function since reset.c is build unconditionally. Add a check in Makefile to build this file only if SYSRESET isn't enabled. SYSRESET can be enabled when building SYSRESET_PSCI for instance on this platform.

2021-06-07Revert "sama5d3: Fix Galois Field Table offsets"Tudor Ambarus1-2/+2
This reverts commit 786f888b743e9b83c9095cb9b5548ebe2e29afc5. Looks like the datasheet at https://ww1.microchip.com/downloads/en/DeviceDoc/SAMA5D3-Series-Data-sheet-DS60001609b.pdf is wrong, and the testing was poorly done, because the PMECC did not raise any error, but also didn't correct any bitflips. Restoring the offsets as they were before, makes the PMECC on sama5d3x capable of correcting bitflips.

This commit does the same thing as Linux commit 33def8498fdd. Use a more generic form for __section that requires quotes to avoid complications with clang and gcc differences. Remove the quote operator # from compiler_attributes.h __section macro. Convert all unquoted __section(foo) uses to quoted __section("foo"). Also convert __attribute__((section("foo"))) uses to __section("foo") even if the __attribute__ has multiple list entry forms.

2021-03-22ARM: mach-at91: arm926ejs: fix data abort in startup returning from ↵Martin Townsend1-8/+8
lowlevel_init The startup code in arm/cpu/arm926ejs preserves the link register across the call to lowlevel_init by using r4: mov r4, lr /* perserve link reg across call */ bl lowlevel_init /* go setup pll,mux,memory */ mov lr, r4 /* restore link */ The lowlevel_init function for at91 machines based on the same CPU uses r4 and hence corrupts it causing a data abort when it returns to the startup code. This patch fixes this by using r6 instead of r4 in the lowlevel_init function. Discovered and the fix was tested on a AT91SAM9261 based board.

2021-03-02reset: Remove addr parameter from reset_cpu()Harald Seiler3-3/+3
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 <hws@denx.de> Reviewed-by: Simon Glass <sjg@chromium.org>

2021-01-05dm: Rename U_BOOT_DEVICE() to U_BOOT_DRVINFO()Simon Glass2-2/+2
The current macro is a misnomer since it does not declare a device directly. Instead, it declares driver_info record which U-Boot uses at runtime to create a device. The distinction seems somewhat minor most of the time, but is becomes quite confusing when we actually want to declare a device, with of-platdata. We are left trying to distinguish between a device which isn't actually device, and a device that is (perhaps an 'instance'?) It seems better to rename this macro to describe what it actually is. The macros is not widely used, since boards should use devicetree to declare devices. Rename it to U_BOOT_DRVINFO(), which indicates clearly that this is declaring a new driver_info record, not a device. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-07-10drivers: rename drivers to match compatible stringWalter Lozano2-8/+8
When using OF_PLATDATA, the bind process between devices and drivers is performed trying to match compatible string with driver names. However driver names are not strictly defined, and also there are different names used when declaring a driver with U_BOOT_DRIVER, the name of the symbol used in the linker list and the used in the struct driver_info. In order to make things a bit more clear, rename the drivers names. This will also help for further OF_PLATDATA improvements, such as checking for valid driver names.

2019-12-15dm: gpio: Allow control of GPIO uclass in SPLSimon Glass1-1/+1
At present if CONFIG_SPL_GPIO_SUPPORT is enabled then the GPIO uclass is included in SPL/TPL without any control for boards. Some boards may want to disable this to reduce code size where GPIOs are not needed in SPL or TPL. Add a new Kconfig option to permit this. Default it to 'y' so that existing boards work correctly. Change existing uses of CONFIG_DM_GPIO to CONFIG_IS_ENABLED(DM_GPIO) to preserve the current behaviour. Also update the 74x164 GPIO driver since it cannot build with SPL. This allows us to remove the hacks in config_uncmd_spl.h and Makefile.uncmd_spl (eventually those files should be removed).
