[U-Boot] buildman for sandbox
by Joe Hershberger 13 Mar '16

13 Mar '16

Hi Simon, Is there a way to make buildman compile sandbox with a non-system tool chain? I've tried creating an alias from sandbox to i386 and removing the "root" entry. It then simply claims not to have a sandbox tool chain. Thanks, -Joe

[U-Boot] [PATCH v1 1/3] fastboot: OUT transaction length must be aligned to wMaxPacketSize
by Dileep Katta 11 Mar '16

11 Mar '16

OUT transactions must be aligned to wMaxPacketSize for each transfer, or else transfer will not complete successfully. This patch modifies rx_bytes_expected to return a transfer length that is aligned to wMaxPacketSize. Note that the value of ep->desc->wMaxPacketSize and ep->maxpacket may not be the same value, and it is the value of ep->desc->wMaxPacketSize that should be used for alignment.

Hi Simon, When I try to run Buildman against a branch named "test", it fails with a weird error message. $ git branch * master $ git checkout -b test master Switched to a new branch 'test' $ echo foo >> README $ git add README $ git commit -m foo [test f8f6569] foo 1 file changed, 1 insertion(+) $ tools/buildman/buildman -b test Branch 'test' not found $ git branch master * test Indeed, the branch "test" exists, but Buildman reports "Branch "test' not found".

[U-Boot] [PATCH 0/4 v4] arm: socfpga: Add Cadence QSPI support
by Stefan Roese 14 Jan '16

14 Jan '16

Hi! So this is my 4th posting regarding the Candence SPI driver on SoCFPGA. Again, SPI NOR flash is working. At least on SoCrates and on another custom SoCFPGA based board. The main change in this version is, that the Cadence driver now is a driver model (DM) based driver. And this needs the DT support which I posted just before. One of the reasons to enable DT support in SoCFPGA is, that I need to support multiple different SPI controllers for this platform. This is the QSPI Cadence controller and the Designware SPI master controller. Both are implemented in the SoCFPGA. And enabling both controllers is only possible by using the new driver model (DM). The DM SPI code only supports DT based probing. So it was easier to move SoCFPGA to DT than to add the (deprecated) platform-data based probing to the DM SPI suport. Note that I have patches to support the Designware SPI master controller also via DM in the queue. I'll post them shortly.

[U-Boot] [PATCH] ARM: UniPhier: add initrd_high and fdt_high environments
by Masahiro Yamada 18 Dec '15

18 Dec '15

With FIT boot, U-boot puts a device tree and an initramdisk at the tail of the memory. Some UniPhier boards have a large amount of memory. For those boards, a device tree and an initramdisk are located out of reach of the Linux kernel causing a kernel panic if CONFIG_VMSPLIT_3G is defined in the kernel side. Add initrd_high and fdt_high to prevent them from going too high.
