This means tree switch conversions and jump tables will not work. Disable these in the CFLAGS for this file. This fixes a crash in am335x_sdram_size() with newer gcc versions.

2019-11-11	0c7c5c2 Browse files » ARM: am335x: Enable MMC2 clock ... Since Kernel commit 5b63fb90adb9 ("ARM: dts: Fix incomplete dts data for am3 and am4 mmc") (barebox commit 419db1f984 ("dts: update to v5.3-rc7")) the AM33xx MMC2 controller is unconditionally enabled in the dts. This has the effect that the driver probes for this device and then can't access the registers as the clock is disabled. Enable the clock to let the driver probe successfully.

This only works when the XN bit is not set for this area, so remap the first MiB as cached which doesn't have the XN bit set.

	52cc061 Browse files » ARM: dts: stm32mp: report psci v0.2 at least ... ARM TF-A reports compatibility with PSCI v1.1 since v1.5. Upstream ARM TF-A support for STM32MP was introduced with v1.6. It's thus safe to assume that the STM32MP barebox will never have to interact with a secure monitor implementing PSCI v0.1. Overwrite the psci device tree compatible to specify v0.2. This is the first version that implements PSCI_VERSION, which allows the barebox psci client driver selected in this commit to query the actual PSCI version and fix it up into the device tree. This fixes an issue where resetting via PSCI fails in Linux because the upstream device tree compatible: reboot: Restarting system Reboot failed -- System halted Reported-by: Michael Olbrich <mol@pengutronix.de> Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Ahmad Fatoum authored on 6 Nov 2019 Sascha Hauer committed on 7 Nov 2019

While at it, remove the unimplemented -z option. It's unneeded, because -c turns off the CPU after starting it again already. Also it seems it's not implementable without interprocessor communication, which is probably overkill here.
