Re: [U-Boot] [PATCH v2]net: Wrong Initialization in davinci-emac driver

29 Jan '16

Author: Vishwas Srivastava <vishu.kernel(a)gmail.com> Date: Mon Jan 25 21:28:17 2016 +0530 Wrong Initialization in davinci emac driver emac module of the davinci platform supports only 8 tx and 8 rx channels (total 16). emac driver for davinci platform, however, while doing initialization of the dma descriptor head pointers,wrongly initializes the 16 head pointers (instead of 8) for tx dma and 16 head pointers(insted of 8) for rx dma, which is wrong.The result is, that this register initilization spills over the other registers which was not intended and is undesirable.This patch fixes this problem.

[U-Boot] [PATCH 0/2] dfu: samsung: Commits to allow sending and storing large files via DFU
by Lukasz Majewski 29 Jan '16

29 Jan '16

Those commits allow sending and storing large files (e.g. 26 MiB) on the Odroid XU3 board. On purpose they are sent together to shed light on the process of tunning board to be capable of large files transfer. I would be _REALLY_ grateful for excessive testing, since I'm not able to test this code on NAND based devices. Please support me and test this patch for potential regressions. This change applies on the u-boot-master tree.

Please post it to the list and cc Pantelis. But also keep in mind you've found and fixed a generic manual reloc problem so you don't need to guard things with NDS32 tests as well.

[U-Boot] [PATCH] autoboot.c: Fill env vars in process_fdt_options() only if TEXT_BASE is set
by Stefan Roese 29 Jan '16

29 Jan '16

The x86 build target "efi-x86" has no TEXT_BASE configured. And with the introduction of CONFIG_BOOTDELAY for x86, this function is now called for this board as well. Resulting in compile errors for this target. Without TEXT_BASE it makes no sense to fill these values. So lets only configure the env variable if TEXT_BASE is defined.

It seems like the P5 header was not present on "Model B" any board prior to Revision 2.0, there's no need for a separate device tree. Also, it looks like "rev2" is incorrectly used to only cover the 512MiB memory models; there also were 256MiB 2.0 boards. I don't have all of the boards to check this, I'm following this table: http://elinux.org/RPi_HardwareHistory#Board_Revision_History --- board/raspberrypi/rpi/rpi.c | 20 ++++++++++---------- 1 file changed, 10 insertions(+), 10 deletions(-) diff --git a/board/raspberrypi/rpi/rpi.c b/board/raspberrypi/rpi/rpi.c index 4b80d7b..b344362 100644 --- a/board/raspberrypi/rpi/rpi.c +++ b/board/raspberrypi/rpi/rpi.c @@ -110,28 +110,28 @@ static const struct rpi_model rpi_models_new_scheme[] = { static const struct rpi_model rpi_models_old_scheme[] = { [0x2] = { - "Model B (no P5)", - "bcm2835-rpi-b-i2c0.dtb", + "Model B", + "bcm2835-rpi-b.dtb", true, }, [0x3] = { - "Model B (no P5)", - "bcm2835-rpi-b-i2c0.dtb", + "Model B", + "bcm2835-rpi-b.dtb", true, }, [0x4] = { - "Model B", - "bcm2835-rpi-b.dtb", + "Model B rev2", + "bcm2835-rpi-b-rev2.dtb", true, }, [0x5] = { - "Model B", - "bcm2835-rpi-b.dtb", + "Model B rev2", + "bcm2835-rpi-b-rev2.dtb", true, }, [0x6] = { - "Model B", - "bcm2835-rpi-b.dtb", + "Model B rev2", + "bcm2835-rpi-b-rev2.dtb", true, }, [0x7] = { -- 2.5.0
