Add support for generic BCM SoC chipsets 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>

ARM: bcm: clean up config and build targets Currently CONFIG_ARCH_BCM_MOBILE is used to select all (both) Broadcom mobile SoC families. Instead, use that only as a config menu switch, and define specific symbols like ARCH_BCM_281XX to select a particular SoC family. If ARCH_BCM_MOBILE is selected, all of the SoCs will be selected by default, but this way each can be disabled individually as well. Note that BCM281xx and BCM21664 both require the SMC and L2 cache control code, so that code will be built based on ARCH_BCM_MOBILE.

ARM: add SMP support for Broadcom mobile SoCs This patch adds SMP support for BCM281XX and BCM21664 family SoCs. This feature is controlled with a distinct config option such that an SMP-enabled multi-v7 binary can be configured to run these SoCs in uniprocessor mode. Since this SMP functionality is used for multiple Broadcom mobile chip families the config option is called ARCH_BCM_MOBILE_SMP (for lack of a better name). On SoCs of this type, the secondary core is not held in reset on power-on. Instead it loops in a ROM-based holding pen. To release it, one must write into a special register a jump address whose low-order bits have been replaced with a secondary core's id, then trigger an event with SEV. On receipt of an event, the ROM code will examine the register's contents, and if the low-order bits match its cpu id, it will clear them and write the value back to the register just prior to jumping to the address specified. The location of the special register is defined in the device tree using a "secondary-boot-reg" property in a node whose "enable-method" matches.

ARM: bcm: config option for l2 cache support Add a new config option ARCH_BCM_MOBILE_L2_CACHE that allows support for level-2 cache to be enabled or disabled at build time for BCM218XX and BCM21664 family SoCs. Build support for SMC only if it's required (currently it's only required for to support level 2 cache control). If arch/arm/mach-bcm/kona.c gets compiled, ARCH_BCM_MOBILE_L2_CACHE must have been selected, which implies CONFIG_CACHE_L2X0 is set. There is therefore no need to check CONFIG_CACHE_L2X0 at the top of kona_l2_cache_init(), so get rid of that check.

# Support for secure monitor traps
ARM: bcm: use inline assembly for "smc" request Move the code that implements the "smc" call into a C function that uses inline assembly. This allows us to make that function private, and enables us to get rid of "arch/arm/mach-bcm/bcm_kona_smc_asm.S". Rename what had been the "buffer_addr" argument to be "buffer_phys" so it's consistent with other usage in this file. Since it's now easy to do, verify that r12 contains SEC_EXIT_NORMAL upon completion of the SMC. There really isn't a good way to handle the abnormal completion of a secure monitor request. Since "bcm_kona_smc.h" is now only included from C files, eliminate the #ifndef __ASSEMBLY__.

ARM: BCM5301X: initial support for the BCM5301X/BCM470X SoCs with ARM CPU This patch adds support for the BCM5301X/BCM470X SoCs with an ARM CPUs. Currently just booting to a shell is working and nothing else, no Ethernet, wifi, flash, ... I have some pending patches to make Ethernet work for this device. Mostly device tree support for bcma is missing. This SoC is used in small office and home router with Broadcom SoCs it's internal name is Northstar. This code should support the BCM4707, BCM4708, BCM4709, BCM53010, BCM53011 and BCM53012 SoC. It uses one or two ARM Cortex A9 Cores, some highlights are 2 PCIe 2.0 controllers, 4 Gigabit Ethernet MACs and a USB 3.0 host controller. This SoC uses a dual core CPU, but this is currently not implemented.
