[U-Boot] [PATCH 0/4] Let the distro boot command scan all partitions
by Sjoerd Simons 02 Feb '15

02 Feb '15

Not all devices use the convention of the first partition holding the boot files. E.g. on chromebooks partition 1 and 2 are usually of the "Chromeos kernel data" type. So instead of hardcoding just the first partitions scan all partition on a storage device. First two patches add some supporting commands, which help in determining the list of partitions to scan and detect whether they have a known filesystem (No need to scan for a bunch of different fiels if the filesystem isn't supported). Third patch has the actual changes, while the last one tries to make it a bit easier for board files to include the distro boot commands even if they don't use it as their default. Sjoerd Simons (4): fs: Add command to retrieve the filesystem type part: let list put the list in an environment variable config_distro_bootcmd: Scan all partitions for boot files distro_distro_bootcmd: use CONFIG_BOOTCOMMAND instead of setting bootcmd= common/cmd_fs.c | 15 +++++++++++++++ common/cmd_part.c | 24 ++++++++++++++++++++++-- fs/fs.c | 27 +++++++++++++++++++++++++++ include/config_distro_bootcmd.h | 21 +++++++++++++++++---- include/fs.h | 6 ++++++ 5 files changed, 87 insertions(+), 6 deletions(-) -- 2.1.4

[U-Boot] [PATCH] video: sunxi: Enable cache for the framebuffer
by Siarhei Siamashka 02 Feb '15

02 Feb '15

Because the framebuffer resides in a hidden chopped off part of DRAM, caching is not enabled for this area automatically when the MMU is configured. So it needs to be set explicitly. Additionally, the cfb console has a function to check whether the framebuffer resides in DRAM or not. And the hidden sunxi framebuffer needs special treatment again. This fix resolves the sluggish scrolling problem.

Maybe if this files wasn't conditional? Assuming the the 'BSS' is aligned (LDS enforced), ldr r0, =__bss_start /* this is auto-relocated! */ ldr r1, =__bss_end /* this is auto-relocated! */ + mov r2, #0 /* prepare zero to clear BSS */ + mov r3, #0 + mov r4, #0 + mov r5, #0 + mov r6, #0 + mov r7, #0 + mov r8, #0 + mov lr, #0 + b 1f + .align 4 clbss_l: + stmia r0!, {r2-r8,lr} /* clear 32 BSS word */ + stmia r0!, {r2-r8,lr} /* easy to unroll */ + 1: cmp r0, r1 blo clbss_l The code should work on all ARM versions? Then every platform would benefit. I think the larger portion of the 'ARCH memset' is to handle alignment issues. Sometimes the tail/head portion can be handled efficiently with 'strd', etc which is only on some CPUs. It is easy to setup the BSS so that both the head/tail are aligned.... but I think the above code only requires multiples of 32bytes as total BSS size (it is easy to jump into the middle of an unrolled loop with 'add pc, rn<<2, #constant'). The size/iteration can be easily tweaked (8/16/32 bytes). At least in principal *if* there is some size alignment on BSS it is fairly easy to write some generic ARM to quickly clear the BSS that will be just as competitive as any ARCH memset version. The above code is adding about 13 words of code. Fwiw, Bill Pringlemeir.

[U-Boot] [PATCH v2 0/6] keymile: enhance IVM reading
by Valentin Longchamp 02 Feb '15

02 Feb '15

All Keymile boards have an EEPROM that is called IVM that contain information about the board that is progammed at production time. One piece of information is the MAC addresses assigned to the board. u-boot requires the MAC address of the ethernet interfaces it uses to be defined when the interface is intialized. This is most of the time read from the environment but in the case where only the default environment is available, this must be read from somewhere else, in our case the IVM. This patch series splits the reading and analysis of the IVM content in 2, so that the IVM content and MAC addresses can be read prior to ethernet initialization. The analysis of the rest of the IVM content still happens at a later second stage. Changes in v2: - Include the first patch, which was forgotten in the first submission Valentin Longchamp (6): KM/IVM: split the IVM reading and parsing in 2 parts kirkwood/km_arm: read the IVM eeprom earlier 85xx/kmp204x: read the IVM eeprom earlier 83xx/km83xx: read the IVM eeprom earlier 82xx/km82xx: read the IVM eeprom earlier KM/IVM: remove ivm_read_eeprom(void) board/keymile/common/common.h | 3 +- board/keymile/common/ivm.c | 77 +++++++++++++++++++++++++---------------- board/keymile/km82xx/km82xx.c | 10 +++++- board/keymile/km83xx/km83xx.c | 5 ++- board/keymile/km_arm/km_arm.c | 6 +++- board/keymile/kmp204x/kmp204x.c | 5 ++- include/configs/km82xx.h | 2 ++ 7 files changed, 73 insertions(+), 35 deletions(-) -- 1.8.0.1

[U-Boot] [PATCH v3] sunxi: Add Linksprite_pcDuino3_Nano board / defconfig
by Adam Sampson 02 Feb '15

02 Feb '15

This is a low-cost Allwinner A20 board with Arduino-style GPIO headers; it features 1G RAM, 4G NAND flash, 1 micro-SD, 2 USB sockets, 1 micro USB socket for OTG and another for power in, HDMI, SATA, 5V power for SATA devices, gigabit Ethernet, an IR receiver, 3.5mm audio out and a MIPI camera connector. Like the BananaPi, this board needs GMAC_TX_DELAY set to 3 in order for GMAC to work reliably at gigabit speeds. For more details, see: http://linux-sunxi.org/LinkSprite_pcDuino3_Nano Changed in v3: - add CONFIG_GMAC_TX_DELAY=3, which corresponds to a patch in LinkSprite's A20 kernel; testing shows the performance is now much better at 1000M Signed-off-by: Adam Sampson <ats(a)offog.org> --- board/sunxi/MAINTAINERS | 5 +++++ configs/Linksprite_pcDuino3_Nano_defconfig | 11 +++++++++++ 2 files changed, 16 insertions(+) create mode 100644 configs/Linksprite_pcDuino3_Nano_defconfig diff --git a/board/sunxi/MAINTAINERS b/board/sunxi/MAINTAINERS index 9050059..44f57ad 100644 --- a/board/sunxi/MAINTAINERS +++ b/board/sunxi/MAINTAINERS @@ -81,6 +81,11 @@ M: Zoltan Herpai <wigyori(a)uid0.hu> S: Maintained F: configs/Linksprite_pcDuino_defconfig +LINKSPRITE-PCDUINO3-NANO BOARD +M: Adam Sampson <ats(a)offog.org> +S: Maintained +F: configs/Linksprite_pcDuino3_Nano_defconfig + MARSBOARD-A10 BOARD M: Aleksei Mamlin <mamlinav(a)gmail.com> S: Maintained diff --git a/configs/Linksprite_pcDuino3_Nano_defconfig b/configs/Linksprite_pcDuino3_Nano_defconfig new file mode 100644 index 0000000..4baba14 --- /dev/null +++ b/configs/Linksprite_pcDuino3_Nano_defconfig @@ -0,0 +1,11 @@ +CONFIG_SPL=y +CONFIG_SYS_EXTRA_OPTIONS="AXP209_POWER,SUNXI_GMAC,RGMII,AHCI,SATAPWR=SUNXI_GPH(2),USB_EHCI" +CONFIG_FDTFILE="sun7i-a20-pcduino3-nano.dtb" +CONFIG_GMAC_TX_DELAY=3 +CONFIG_USB1_VBUS_PIN="PH11" ++S:CONFIG_ARM=y ++S:CONFIG_ARCH_SUNXI=y ++S:CONFIG_MACH_SUN7I=y ++S:CONFIG_DRAM_CLK=408 ++S:CONFIG_DRAM_ZQ=122 ++S:CONFIG_DRAM_EMR1=4 -- 2.2.2
