[U-Boot] [PATCH 9/9] tegra124: Reserve secure RAM using MC_SECURITY_CFG{0, 1}_0

From: Ian Campbell These registers can be used to prevent non-secure world from accessing a megabyte aligned region of RAM, use them to protect the u-boot secure monitor code. At first I tried to do this from s_init(), however this inexplicably causes u-boot's networking (e.g. DHCP) to fail, whi

[U-Boot] [PATCH 7/9] tegra124: Add PSCI support for Tegra124

From: Jan Kiszka This is based on Thierry Reding's work and uses Ian Campell's preparatory patches. It comes with full support for CPU_ON/OFF PSCI services. The algorithm used in this version for turning CPUs on and off was proposed by Thierry Reding in http://thread.gmane.org/gmane.comp.boot-loa

[U-Boot] [PATCH 3/9] tegra124: Add more registers to struct mc_ctlr

[U-Boot] [PATCH 8/9] jetson-tk1: Add PSCI configuration options and reserve secure code

From: Ian Campbell The secure world code is relocated to the MB just below the top of 4G, we reserve it in the FDT (by setting CONFIG_ARMV7_SECURE_RESERVE_SIZE) but it is not protected in h/w. See next patch. Signed-off-by: Ian Campbell Signed-off-by: Jan Kiszka --- arch/arm/cpu/armv7/tegra12

[U-Boot] [PATCH 4/9] virt-dt: Allow reservation of the secure region when it is in a RAM carveout.

From: Ian Campbell In this case the secure code lives in RAM, and hence needs to be reserved, but it has been relocated, so the reservation of __secure_start does not apply. Add support for setting CONFIG_ARMV7_SECURE_RESERVE_SIZE to reserve such a region. This will be used in a subsequent patc

[U-Boot] [PATCH 0/9] Add PSCI support for Jetson TK1/Tegra124

I've picked up Ian's and Thierry's work on PSCI support for Tegra124, specifically the Jetson TK1 board. This series contains Ian's patches and a rewritten version of the PSCI core as suggested by Thierry. It's working fine on the TK1, allowing Linux to online/offline CPUs 1-3 as it likes (provided

[U-Boot] [PATCH 1/9] ARM: Factor out reusable psci_cpu_off_common

From: Jan Kiszka Move parts of sunxi's psci_cpu_off into psci_cpu_off_common, namely cache disabling and flushing, clrex and the disabling of SMP for the dying CPU. These steps are apparently generic for ARMv7 and will be reused for Tegra124 support. Signed-off-by: Jan Kiszka --- arch/arm/cpu/
