[U-Boot] [PATCH 1/3][v3] Pointers in ESBC header made 32 bit
by Aneesh Bansal 23 Feb '16

23 Feb '16

For the Chain of Trust, the esbc_validate command supports 32 bit fields for location of the image. In the header structure definition, these were declared as pointers which made them 64 bit on a 64 bit core.

[U-Boot] [PATCH V6] sf: Turn SPI flash chip into 3-Byte address mode
by Zhiqiang Hou 27 Jan '16

27 Jan '16

From: Hou Zhiqiang <B48286(a)freescale.com> For more than 16MiB SPI flash chips, there are 3-Byte and 4-Byte address mode, and only the 3-Byte address mode is supported in U-Boot so far. So, reset the SPI flash to 3-Byte address mode in probe to ensure the SPI flash work correctly, because it may has been set to 4-Byte address mode after warm boot. Signed-off-by: Hou Zhiqiang <B48286(a)freescale.com> --- Tested on T1042RDB board. V6: Add the spi_release_bus. V5: 1. Removed #ifdef for STMICRO. 2. Add support for Spansion chips (>16MiB) switch to 3-Byte address mode. V4: Split the the patch to 2 patches for clear FSR and SPI flash address mode. V3: Generate the patch based on the latest tree git://git.denx.de/u-boot.git. V2: Add the operation of enter 3 Byte address mode in probe.

[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] 2TB disks
by Stefan Monnier 13 Jan '16

13 Jan '16

I just bumped into a problem where U-Boot refused to boot from my disk's second partition because the sector number is "negative". More specifically, my disk drive is 2TB, which means that the number of 512B blocks fits into an unsigned 32bit int but not into a signed 32bit int. U-boot's "scsi part" displays the size (in blocks) correctly, but the size of the first partition (which is around 1.8TB) is printed as a negative number, and so is the start sector of the second partition. This was tested on a BananaPi using v2015-07. Stefan

[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.

[U-Boot] [PATCH 1/5] Make RBTREE selectable by Kconfig
by Lars Poeschel 16 Dec '15

16 Dec '15

Users who want to use RBTREE can now select it by Kconfig. Selecting it by board config include is still possible.
