2015-04-09pistachio: implement timer supportVadim Bendebury
C0_COUNT register is a free running counter clocked by the CPU frequency divided by two. On the FPGA board it results in 25 MHz, on real SOCs it will have to be figured out later. Some magic addresses and numbers are used to find out if the code is running on the FPGA board. timestamp_get() and timer_monotonic_get() are kept in the same file. The CPU initialization makes sure that CO COUNT is in fact enabled and starts from zero. BRANCH=none BUG=chrome-os-partner:33595,chrome-os-partner:31438 TEST=with timer enabled, the startup code properly initializes UART and prints the coreboot bootblock banner message on the serial console.

2015-04-06New mechanism to define SRAM/memory map with automatic bounds checkingJulius Werner
This patch creates a new mechanism to define the static memory layout (primarily in SRAM) for a given board, superseding the brittle mass of Kconfigs that we were using before. The core part is a memlayout.ld file in the mainboard directory (although boards are expected to just include the SoC default in most cases), which is the primary linker script for all stages (though not rmodules for now). It uses preprocessor macros from <memlayout.h> to form a different valid linker script for all stages while looking like a declarative, boilerplate-free map of memory addresses to the programmer. Linker asserts will automatically guarantee that the defined regions cannot overlap. Stages are defined with a maximum size that will be enforced by the linker. The file serves to both define and document the memory layout, so that the documentation cannot go missing or out of date. The mechanism is implemented for all boards in the ARM, ARM64 and MIPS architectures, and should be extended onto all systems using SRAM in the future. The CAR/XIP environment on x86 has very different requirements and the layout is generally not as static, so it will stay like it is and be unaffected by this patch (save for aligning some symbol names for consistency and sharing the new common ramstage linker script include). BUG=None TEST=Booted normally and in recovery mode, checked suspend/resume and the CBMEM console on Falco, Blaze (both normal and vboot2), Pinky and Pit. Compiled Ryu, Storm and Urara, manually compared the disassemblies with ToT and looked for red flags.

2015-04-02urara: Fix CBFS header definitionsVadim Bendebury
Urara CBFS header configuration is broken. CBFS header needs to be right above the bootblock, and the CBFS data - 0x100 bytes above, to allow room for proper CBFS wrapper structures.

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>
