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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | reset: Remove addr parameter from reset_cpu()Harald Seiler2021-03-023-3/+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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
