2018-06-26soc: bcm: brcmstb: Add missing DDR MEMC compatible stringsFlorian Fainelli1-0/+3
We would not be matching the following chip/compatible strings combinations, which would lead to not setting the warm boot flag correctly, fix that: 7260A0/B0: brcm,brcmstb-memc-ddr-rev-b.2.1 7255A0: brcm,brcmstb-memc-ddr-rev-b.2.3 7278Bx: brcm,brcmstb-memc-ddr-rev-b.3.1 The B2.1 core (which is in 7260 A0 and B0) doesn't have the SHIMPHY_ADDR_CNTL_0_DDR_PAD_CNTRL setup in the memsys init code, nor does it have the warm boot flag re-definition on entry. Those changes were for B2.2 and later MEMSYS cores. Fall back to the previous S2/S3 entry method for these specific chips.

Pull ARM SoC driver updates from Arnd Bergmann: "This branch contains platform-related driver updates for ARM and ARM64, these are the areas that bring the changes: New drivers: - driver support for Renesas R-Car V3M (R8A77970) - power management support for Amlogic GX - a new driver for the Tegra BPMP thermal sensor - a new bus driver for Technologic Systems NBUS Changes for subsystems that prefer to merge through arm-soc: - the usual updates for reset controller drivers from Philipp Zabel, with five added drivers for SoCs in the arc, meson, socfpa, uniphier and mediatek families - updates to the ARM SCPI and PSCI frameworks, from Sudeep Holla, Heiner Kallweit and Lorenzo Pieralisi Changes specific to some ARM-based SoC - the Freescale/NXP DPAA QBMan drivers from PowerPC can now work on ARM as well - several changes for power management on Broadcom SoCs - various improvements on Qualcomm, Broadcom, Amlogic, Atmel, Mediatek - minor Cleanups for Samsung, TI OMAP SoCs" [ NOTE! This doesn't work without the previous ARM SoC device-tree pull, because the R8A77970 driver is missing a header file that came from that pull.

Commit 84320e1a635fcf90cff4185f029ce9e31bf1d4a7 ("ARM: BCM: Clean up SMP support for Broadcom Kona") moved the "secondary-boot-reg" property from the "cpus" node to the individual "cpu" nodes but negelected to update brcm,bcm11351-cpu-method.txt to match. bcm11351-cpu-method was apparently never added to the list of methods in bindings/arm/cpus.txt. bindings/arm/cpus.txt states that "enable-method" should be a property of the "cpu" node rather than the "cpus" node.

Broadcom mobile SoCs use a ROM-implemented holding pen for controlled boot of secondary cores. A special register is used to communicate to the ROM that a secondary core should start executing kernel code. This enable method is currently used for members of the bcm281xx and bcm21664 SoC families. The use of an enable method also allows the SMP operation vector to be assigned as a result of device tree content for these SoCs.

2012-11-19Add support for generic BCM SoC chipsetsChristian Daudt1-0/+9
In order to start upstreaming Broadcom SoC support, create a starting hierarchy, arch and dts files. The first support SoC family that is planned is the BCM281XX (BCM11130/11140/11351/28145/28155) family of dual A9 mobile SoC cores. This code is just the skeleton code for get the machine upstreamed. It has been made MULTIPLATFORM compatible. Next steps ---------- Upstream a basic set of drivers - sufficient for a console boot to ramdisk. These will includer timer, gpio, i2c drivers. After this basic set, we will proceed with a more comprehensive set of drivers for the 281XX SoC family. v2 patch mods -------- - Remove l2x0_of_init call as there were problems with the code. A separate patch will be submitted with cache init code - Rename capri files and refs to bcm281xx-based names - Add bcm281xx binding doc - various misc cleanups v3 patch mods ------------- - Remove extra #include lines - Remove remaining references to capri - dt uart chipset string added - cleaned up chip # references v4 patch mods ------------- - swap order of compatible definitions for uart - fix typo v5 patch mods ------------- - Rename bcm281xx to bcm11351 in dts+code, leaving references to bcm281xx only in help+comments. v6 patch mods ------------- - fix typo in uart 'compatible' string Signed-off-by: Christian Daudt <csd@broadcom.com> Reviewed-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Olof Johansson <olof@lixom.net>
