[U-Boot] U-boot UBI breaks build with -O0
by Kevin Smith 17 Sep '15

17 Sep '15

Some of the debug functions for UBI are preprocessed out for U-boot (ifndef __UBOOT__), but their calls are optimized out at higher optimization levels, so this does not cause a problem. When building with -O0, the linker gives an error: fs/ubifs/io.c:162: undefined reference to `dbg_leb_unmap' This function is in a #ifndef __UBOOT__ section. Kevin Smith

[U-Boot] [PATCH] Revert "fdt: Fix fdtdec_get_addr_size() for 64-bit"
by Simon Glass 17 Sep '15

17 Sep '15

This reverts commit 5b34436035fc862b5e8d0d2c3eab74ba36f1a7f4. This function has a few problems. It calls fdt_parent_offset() which as mentioned in code review is very slow. https://patchwork.ozlabs.org/patch/499482/ https://patchwork.ozlabs.org/patch/452604/ It also happens to break SPI flash on Minnowboard max which is how I noticed that this was applied. I can send a patch to tidy that up, but in any case I think we should consider a revert until the function is better implemented.

[U-Boot] [PATCH] arm: ls1021a: Add QSPI or IFC support in SD boot
by Alison Wang 17 Sep '15

17 Sep '15

As QSPI and IFC are pin-multiplexed on LS1021A, only IFC is supported in SD boot now. For the customer's demand, QSPI needs to be supported in SD boot too. This patch adds QSPI or IFC support in SD boot according to the corresponding defconfig. For detail, ls1021atwr_sdcard_ifc_defconfig is used to support IFC in SD boot and ls1021atwr_sdcard_qspi_defconfig is used to support QSPI in SD boot.

[U-Boot] [PATCH V2 0/4] drivers/sandbox: Introduce a simplified remoteproc framework
by Nishanth Menon 17 Sep '15

17 Sep '15

Many System on Chip(SoC) solutions are complex with multiple processors on the same die dedicated to either general purpose of specialized functions. Many examples do exist in today's SoCs from various vendors. Typical examples are micro controllers such as an ARM M3/M0 doing a offload of specific function such as event integration or power management or controlling camera etc. Traditionally, the responsibility of loading up such a processor with a firmware and communication has been with a High Level Operating System(HLOS) such as Linux. However, there exists classes of products where Linux would need to expect services from such a processor or the delay of Linux and operating system being able to load up such a firmware is unacceptable. The intent here is to introduce a simplified remoteproc framework which can then be used to provide basic services to these remote processors.

[U-Boot] [PATCH] kbuild: fixdep: drop meaningless hash table initialization
by Masahiro Yamada 16 Sep '15

16 Sep '15

The clear_config() is called just once at the beginning of this program, but the global variable hashtab[] is already zero-filled at the start-up.

[U-Boot] [PATCH] Revert "env_eeprom: Assign default environment during board_init_f"
by Ludger Dreier 16 Sep '15

16 Sep '15

This reverts commit ed6a5d4f880ac248530dbf64683b2257dbe54b64. The original patch uses ENV_IS_EMBEDDED to decide if the default environment should be used or the one actually read from EEPROM. The code in environment.h allows setting of ENV_IS_EMBEDDED only for a subset of flash types. EEPROM is not included in that list. So basically reading environment from I2C EEPROM is broken now. I propose to revert the patch.
