* ARM: beaglebone: init MPU speed to 800MhzMarc Reilly2021-06-151-1/+1
| | | | | | | | | This sets the core processor speed to 800Mhz (from 500). Doing this helps speed the boot up a bit until the CPU freq govenor takes over.

* arch/arm/boards: Replace license and copyright boilerplate by SPDX identfiersUwe Kleine-König2020-05-251-17/+3
| | | | | | | | | | | | | | | | This adapts all files that were identifed by licensecheck (https://salsa.debian.org/build-common-team/licensecheck.git) as licensed under the GPL. The advantage is that these specifiers are machine-parseable which helps license conformance, e.g. for packaging barebox in Debian. While touching these files also do some minor comment reformatting to get some uniform layout.

| * ARM: AM335x: Fix invalid register accessSascha Hauer2018-03-191-20/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several DDR3 phy registers are written with the pattern x<<30 | x<<20 | x<<10 | x. The x<<30 doesn't fit into 32bit which causes a compiler warning. Looking at the reference manual only the lower 10bit of the registers have any meaning, so drop the other bogus values. This affects the registers: AM33XX_DATA0_RD_DQS_SLAVE_RATIO_0 AM33XX_DATA0_WR_DQS_SLAVE_RATIO_0 AM33XX_DATA0_WR_DQS_SLAVE_RATIO_1 AM33XX_DATA0_WRLVL_INIT_RATIO_0 AM33XX_DATA0_GATELVL_INIT_RATIO_0 AM33XX_DATA0_GATELVL_INIT_RATIO_1 AM33XX_DATA0_FIFO_WE_SLAVE_RATIO_0 AM33XX_DATA0_WR_DATA_SLAVE_RATIO_0 (AM33XX_DATA0_WR_DQS_SLAVE_RATIO_1 and AM33XX_DATA0_GATELVL_INIT_RATIO_1 do not even exist according to the reference manual, but that's another story.)

* | ARM: return positive offset in get_runtime_offset()Sascha Hauer2018-03-211-1/+1
|/ | | | | | | | | | | When we are linked at 0x0 and running at 0x01000000 then get_runtime_offset() should return 0x01000000 and not 0xff000000. This makes get_runtime_offset() more consistent and better understandable. This was tested on a Freescale i.MX53 Quickstart board. Additionally relocate_to_adr() was tested since that is normally not called. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* arm: am33xx: Initialize EMIF REG_PR_OLD_COUNTDaniel Schultz2017-01-301-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is based on a patch from the U-Boot and fixes two errors with the LCDC. Original commit message from Jyri Sarha [1]: "Initialize EMIF OCP_CONFIG registers REG_COS_COUNT_1, REG_COS_COUNT_2, and REG_PR_OLD_COUNT field for Beaglebone-Black and am335x-evm. With the default values LCDC suffers from DMA FIFO underflows and frame synchronization lost errors. The initialization values are the highest that work flawlessly when heavy memory load is generated by CPU. 32bpp colors were used in the test. On BBB the video mode used 110MHz pixel clock. The mode supported by the panel of am335x-evm uses 30MHz pixel clock." The register values are generated by testing, because there is no formula to calculate them. Also from Jyri Sarha [1]: "In practice the only rule to find an optimal value is to find as high as possible REG_PR_OLD_COUNT value that does not produce LCDC FIFO underflows under worst case scenario. The worst case happens when the highest pixel clock videomode with maximum bpp is used while memory subsystem is stressed by endless stream of writes hitting the same memory memory bank (can be the same address)." It only contains the BeagleBone Black and the Phytec SoM, because I don't have other boards.

| | | | | | | | | | | | | | | | Commit 0d6392de4ad824a6553c0e3e3e18edef689a7c85 introduced a stripped down device tree used for both white and black Beaglebone variants that included the 256 MiB memory node from am335x-bone-common.dtsi. This leads to the following error in the MLO: mmu: Critical Error: Can't request SDRAM region for ttb at 9fff4000 This patch removes the (for the Beaglebone black) invalid memory size from the common device tree and instead registers the memory bank manually in the board file.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | omap_save_bootinfo derefences the argument passed to barebox without checking it for validity. This breaks 2nd stage booting where r0 is undefined. The best we can do is to check whether the pointer is somewhere in SRAM and is word aligned. This at least makes sure that we do not oops. This introduces SoC specific xxx_save_bootinfo variants since the SRAM addresses/sizes differ between SoCs. Additionally fix the prototype for omap_save_bootinfo. It uses r0, so it must be passed this variable. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* arm: omap: store boot source info from ROM loaderTeresa Gámez2013-07-101-1/+4
| | | | | | | | | | | | | | | | | | The ROM loader passes the address of a buffer to the MLO in register 0. Store this data so we can find the boot source later. On the same way the bootinformation are passed to the barebox, then. It has to be enshured that r0 contains always the buffer or the boot source detection will not work. Applied this on all OMAPs.
