[U-Boot] [PATCH v2 0/2] OMAP/GPMC: speed up NAND read access
by Daniel Mack 13 Jan '15

13 Jan '15

Resending this since I got no replies on the first version. I also fixed up the commit log of #1. ------------ I spent some time looking into boot times of AM335x platforms. One big improvement I made came with adding support for GPMC prefetch mode, which gave a speed-up of NAND reads of roughly factor 2. This is what patch #1 does. Note that this is currently limited to read operations in 8-bit mode, but I believe it could be easily extended to 16-bit operations if anyone has hardware to test it on. Using the engine for write mode speed improvements should also be doable, but I didn't spend time on it yet. That can be added as a separate patch later. Patch #2 decreases the GPMC memory map window size from 256MiB to 16MiB. Admittedly, I'm not quite sure about the reason, but a read from offset 0 in this memory area will freeze U-Boot instantly if the size is configured to 256MiB. As contents of the FIFO are accessed in a pseudo-mode from offset 0 anyway, it doesn't really matter. What I also did to further speed up my boot was to tweak the GPMC parameters for the NAND chip on our boards, but that's not part of this patch set, and probably deserves a little more cleanup. Test results and feedback very welcome.

Hi Tom, I'm not sure of the process for a failed pull request. I have fixed up the offending patch (fdt: Add several apis to decode pci device node) and pushed to to x86/master. The following changes since commit 92fa7f53f1f3f03296f8ffb14bdf1baefab83368: Prepare v2015.01 (2015-01-12 09:39:08 -0500) are available in the git repository at: git://git.denx.de/u-boot-x86.git for you to fetch changes up to 657e384af630463e3c8c4ffbacd16c5e46aeb0e0: x86: Remove CONFIG_DISPLAY_CPUINFO in chromebook_link.h (2015-01-13 07:25:05 -0800) ---------------------------------------------------------------- Bin Meng (25): x86: Remove alex.dts in arch/x86/dts x86: Rename coreboot.dsti to serial.dtsi x86: Clean up the board dts files x86: Add missing DECLARE_GLOBAL_DATA_PTR for pci.c x86: Support pci bus scan in the early phase pci: Make pci apis usable before relocation x86: Simplify the fsp hob access functions fdt: Add several apis to decode pci device node serial: ns16550: Support ns16550 compatible pci uart devices x86: Use ePAPR defined properties for x86-uart x86: crownbay: Add pci devices in the dts file x86: fsp: Drop get_hob_type() and get_hob_length() x86: coreboot: Set up timer base correctly x86: Allow a hardcoded TSC frequency provided by Kconfig x86: Move CONFIG_X86_RESET_VECTOR and CONFIG_SYS_X86_START16 to Kconfig x86: Hide ROM chip size when CONFIG_X86_RESET_VECTOR is not selected x86: coreboot: Make SYS_CONFIG_NAME and DEFAULT_DEVICE_TREE configurable x86: coreboot: Move coreboot-specific defines from coreboot.h to Kconfig x86: Move CONFIG_SYS_CAR_xxx to Kconfig x86: Remove include/configs/coreboot.h x86: Make chromebook_link the default board for coreboot x86: coreboot: Wrap cros_ec initialization x86: coreboot: Configure pci memory regions x86: Update README.x86 for coreboot support x86: Remove CONFIG_DISPLAY_CPUINFO in chromebook_link.h Simon Glass (20): x86: Correct XIP_ROM_SIZE x86: Drop RAMTOP Kconfig x86: Correct ifdtool microcode calculation x86: video: Add a debug() to display the frame buffer address x86: pci: Don't return a vesa mode when there is not video x86: video: Add debug option to time the BIOS copy x86: ivybridge: Only run the Video BIOS when video is enabled x86: Use cache, don't clear the display in video BIOS x86: Tidy up VESA mode numbers x86: pci: Display vesa modes in hex x86: ivybridge: Drop support for ROM caching x86: Add support for MTRRs x86: ivybridge: Set up an MTRR for the video frame buffer x86: board_f: Adjust x86 boot order for performance x86: ivybridge: Request MTRRs for DRAM regions x86: Commit the current MTRRs before relocation x86: ivybridge: Add a way to turn off the CAR x86: Disable CAR before relocation on platforms that need it x86: ivybridge: Update microcode early in boot x86: Add an 'mtrr' command to list and adjust MTRRs arch/x86/Kconfig | 39 +++++- arch/x86/cpu/Makefile | 1 + arch/x86/cpu/coreboot/Kconfig | 15 +++ arch/x86/cpu/coreboot/coreboot.c | 22 ++-- arch/x86/cpu/coreboot/pci.c | 30 ++++- arch/x86/cpu/coreboot/timestamp.c | 33 ++++-- arch/x86/cpu/ivybridge/car.S | 74 +++++++++++- arch/x86/cpu/ivybridge/cpu.c | 27 +---- arch/x86/cpu/ivybridge/gma.c | 16 ++- arch/x86/cpu/ivybridge/microcode_intel.c | 26 ++-- arch/x86/cpu/ivybridge/sdram.c | 10 ++ arch/x86/cpu/mtrr.c | 81 +++++++++++++ arch/x86/cpu/pci.c | 11 +- arch/x86/cpu/queensbay/fsp_support.c | 95 ++++++++------- arch/x86/cpu/queensbay/tnc_dram.c | 39 +++--- arch/x86/cpu/start.S | 8 ++ arch/x86/dts/Makefile | 4 +- arch/x86/dts/alex.dts | 24 ---- arch/x86/dts/chromebook_link.dts | 217 ++++++++++++++++++++++++++++++++- arch/x86/dts/coreboot.dtsi | 17 --- arch/x86/dts/crownbay.dts | 94 +++++++++++++-- arch/x86/dts/link.dts | 224 ----------------------------------- arch/x86/dts/serial.dtsi | 9 ++ arch/x86/include/asm/arch-ivybridge/microcode.h | 6 + arch/x86/include/asm/arch-queensbay/fsp/fsp_hob.h | 68 +++-------- arch/x86/include/asm/arch-queensbay/fsp/fsp_support.h | 5 +- arch/x86/include/asm/global_data.h | 16 ++- arch/x86/include/asm/mtrr.h | 163 ++++++++++++------------- arch/x86/include/asm/pci.h | 2 +- arch/x86/lib/Makefile | 1 + arch/x86/lib/bios.c | 14 ++- arch/x86/lib/cmd_hob.c | 18 +-- arch/x86/lib/cmd_mtrr.c | 138 +++++++++++++++++++++ arch/x86/lib/init_helpers.c | 8 ++ arch/x86/lib/tsc_timer.c | 8 +- board/coreboot/coreboot/Kconfig | 27 ++++- board/coreboot/coreboot/MAINTAINERS | 2 +- board/coreboot/coreboot/coreboot.c | 2 + board/google/chromebook_link/Kconfig | 9 ++ board/intel/crownbay/Kconfig | 1 + common/board_f.c | 8 +- configs/chromebook_link_defconfig | 1 + configs/coreboot-x86_defconfig | 1 -
