2015-03-28arm64: Reinit free_idx to 1 in mmu_initFurquan Shaikh
If mmu_init is called more than once then, free_idx should be reset to 1. Here, the assumption would be that mmu_init will not be called more than once. However, this is not necessarily true. Thus, free_idx should be reset to 1 every time we are initializing ttb from scratch.

Rush builds were throwing a _sync_sp_el0 exception due to commit 65af2f3d (tegra132: support arm64 SMP bringup).

2015-03-27cbfs/rmodule: add architecture specific operations at stage loadIonela Voinescu
Two weak functions were added so that architecture specific operations on each segment of payload or stage can be performed. Each architecture must define its own operations, otherwise the behavior will default to do-nothing functions. This patch has been updated by to fit more in line with how program loading is currently being done. The API is the same as the original, but all call sites to stages/payloads have been updated. This is known to break any archs that use rmodule loading that needs cache maintenance. That will be fixed in a forthcoming patch. Also, the vboot paths are left as is for easier upstreaming of the rest of the vboot patches.

2015-03-27soc/imgtec/pistachio: Add IMGTEC SPI controller driverIonela Voinescu
The Serial Peripheral Flash Interface (SPFI) block allows communication with various devices over the SPI bus. It uses a configurable transaction interface and it clocks the bus according to the configured command, address, gap (aka dummy) and data lengths. This controller requires the SPI_ATOMIC_SEQUENCING flag set (write and read done in the same transaction) as it cannot directly control CS and will assert/de-assert CS at the beginning/end of a transaction itself. Note that the size of any transfer cannot be greater than 64KB - 1, as this is configured in a 16-bit field. The SOC has 2 SPFI interfaces each of them providing 5 slave select lines. SPFI 0 supports single and dual modes, SPFI 1 supports single, dual and quad modes. For SPFI interface 0: - The block needs the system PLL and the following top level SPI clock registers to be set: - CR_cr_top_spi0clkinternal_CTRL[2:0] with division value - CR_MIPS_CLOCK_GATE[19]: bit cr_top_SPI0CLKOUT_MIPS set - CR_cr_top_SPI0CLKOUT_CTRL[6:0] with division value - The following MFIO configuration parameters are also required: Signal name Pad name MFIO mode spim0_d0_txd MFIO_MIPS_10 0 spim0_d1_rxd MFIO_MIPS_9 0 spim0_mclk MFIO_MIPS_8 0 spim0_cs0 MFIO_MIPS_2 1 spim0_cs1 MFIO_MIPS_1 1 spim0_cs2 MFIO_MIPS_55 1 MFIO_MIPS_28 1 spim0_cs3 MFIO_MIPS_56 1 MFIO_MIPS_29 1 spim0_cs4 MFIO_MIPS_57 1 MFIO_MIMPS_30 1 For SPFI interface 1: - The block needs the system PLL and the following top level SPI clock registers to be set: - CR_cr_top_spi1clkinternal_CTRL[2:0] with division value - CR_MIPS_CLOCK_GATE[20]: bit cr_top_SPI1CLKOUT_MIPS set - CR_cr_top_SPI1CLKOUT_CTRL[6:0] with division value - The following MFIO configuration parameters are also required: Signal name Pad name MFIO mode spim1_d0_txd MFIO_MIPS_5 0 spim1_d1_rxd MFIO_MIPS_4 0 spim1_mclk MFIO_MIPS_3 0 spim1_d2 MFIO_MIPS_6 0 spim1_d3 MFIO_MIPS_7 0 spim1_cs0 MFIO_MIPS_0 0 spim1_cs1 MFIO_MIPS_1 0 MFIO_MIPS_58 1 spim1_cs2 MFIO_MIPS_2 0 MFIO_MIPS_55 2 MFIO_MIPS_31 1 spim1_cs3 MFIO_MIPS_56 2 spim1_cs4 MFIO_MIPS_57 2 BUG=chrome-os-partner:31438, chrome-os-partner:32441 TEST=Tested as bare-metal driver on Pistachio FPGA Change-Id: I3b3e4475976e6fba58cef93b12d997ec5cb26341 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Original-Commit-Id: 621849942e27f7d6cf2c8ade7f2c4d18d2318b91 Original-Change-Id: Ib257eb6236bd2895281175871b4ab979660f1239 Original-Signed-off-by: Ionela Voinescu <ionela.voinescu@imgtec.com> Original-Reviewed-on: https://chromium-review.googlesource.com/217320 Original-Reviewed-by: Vadim Bendebury <vbendeb@chromium.org> Reviewed-on: http://review.coreboot.org/9049 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>

Instead of directly using the clk_src_id based on enum for clock source, every device needs to have its own set of clk source ids defined.

2015-03-27tegra132: add spin table supportAaron Durbin
Until PSCI is functional the other core still needs to be brought up in the kernel. The kernel boots these cpus with the spin table which is just an address in memory to monitor a jump location. BUG=chrome-os-partner:31545 BRANCH=None TEST=Built and brought up secondary core in linux.

2015-03-27arm64: provide API for coordinating secondary CPU bringupAaron Durbin
Provides a minimal API for coordinating with the SoC for bringing up the secondary CPUs. There's no eventloop or dispatcher currently nor does it do anything proper when one of the secondary CPUs are brought up. Those decisions are deferred to the SoC. BUG=chrome-os-partner:31545 BRANCH=None TEST=Built and brought up 2nd cpu using this API.
