[U-Boot] [PATCH v3 00/10] binman: A tool for creating firmware images
by Simon Glass 16 Nov '16

16 Nov '16

This series introduces binman, a tool designed to create firmware images. It provides a way to bring together various binaries and place them in an image, at particular positions and with configurable alignment. Packaging of firmware is quite a different task from building the various parts. In many cases the various binaries which go into the image come from separate build systems. For example, ARM Trusted Firmware is used on ARMv8 devices but is not built in the U-Boot tree. If a Linux kernel is included in the firmware image, it is built elsewhere. It is of course possible to add more and more build rules to the U-Boot build system to cover these cases. It can shell out to other Makefiles and build scripts. But it seems better to create a clear divide between building software and packaging it. U-Boot supports a very large number of boards. Many of these have their own specific rules for how an image should be put together so that it boots correctly. At present these rules are described by manual instructions, different for each board. By turning these instructions into a standard format, we can support making valid images for any board without manual effort, lots of READMEs, etc. Images consist of a number of entries which are combined to make up the final image. The image is described in the device tree for the board, meaning that it can be accessed at run-time if desired. Binman is an extensible tool. A set of standard entries is provides, but new entries can be created fairly easily. Entries can be as simple as providing the name of a file to include. They can also handle more complex requirements, such as adjusting the input file or reading header information from one entry to control the position of another. U-Boot's mkimage builds FIT images and various other binaries. Binman augments this by allowing these binaries to be packed together. While FIT should be used where possible, it cannot be used everywhere. For example, many devices require executable code at a particular offset in the image. X86 machines require lots of binary blobs at particular places, and a microcode collection easily accessible at boot. So far binman has enough functionality to be useful, but apart from a few RFC patches, no attempt is made to switch boards over to use it. There should be enough material to permit review and comments. The series is available at u-boot-dm/binman-working Future work and missing features are documented in the README. Changes in v3: - Add a new patch to automatically include a U-Boot .dtsi file - Use a <dts>-u-boot.dtsi file for the binman changes - Put the binman definition in u-boot.dtsi Changes in v2: - Add test for code coverage - drop the unused __len__() method - Fix the -b option - Add automated test coverage - Various changes and improvements based on using this tool for a while - Put the binman

[U-Boot] [PATCH] nand: force BBT scan for controllers which need it
by Stefan Agner 15 Nov '16

15 Nov '16

From: Stefan Agner <stefan.agner(a)toradex.com> Commit 35c204d8a9d0 ("nand: reinstate lazy bad block scanning") introduced lazy BBT scanning. However, some controller do parts of the initialization (mxs_nand.c) during scan_bbt, hence for those controllers the BBT must be scanned at initialization time. In most situation the U-Boot environment gets read first, and the U-Boot environment code checks for bad blocks first. Checking for bad blocks will ask for scan_bbt before reading the first page, hence in most situation the issue does not appear in practice. However, when there is no environment configured, other code might access NAND first which does not explicitly checks for bad blocks, in those cases ECC reads will fail always.

While dealing with large chips (e.g. page: 4KB, OOB:224), we found it helpful to get these additional NAND info by enabling the DEBUG macro instead of full tracing every time and consuming time.

[U-Boot] [v2, 1/5] mmc: fsl_esdhc: don't set XFERTYP_RSPTYP_48_BUSY for CMD with busy response
by Yangbo Lu 14 Nov '16

14 Nov '16

For CMD with busy response, the eSDHC driver would poll DAT0 until CMD completion rather than polling IRQSTAT. So, don't set XFERTYP_RSPTYP_48_BUSY to avoid interrupts (DTOE or TC) in IRQSTAT.

[U-Boot] [PATCH v2 0/5] Raspberry Pi EFI enablement
by Alexander Graf 14 Nov '16

14 Nov '16

This is a follow-up to the RTS patch set from yesterday. With this patch set I can successfully boot a Raspberry Pi 3 into Linux, with efifb, efi based reset/power off and spin table secondary bringup working. I've put all of this into a single patch set so it doesn't get lost. In theory most patches could live by themselves, but it doesn't make much sense to introduce frameworks without adding users to them :). Enjoy, Alex Alexander Graf (5): efi_loader: Allow boards to implement get_time and reset_system ARM: bcm283x: Implement EFI RTS reset_system efi_loader: gop: Expose fb when 32bpp bcm2835 video: Map frame buffer as 32bpp bcm2835: Reserve the spin table in efi memory map arch/arm/mach-bcm283x/include/mach/wdog.h | 2 +- arch/arm/mach-bcm283x/reset.c | 59 +++++++++++++++-- board/raspberrypi/rpi/rpi.c | 6 ++ cmd/bootefi.c | 4 ++ drivers/video/bcm2835.c | 6 +- include/configs/rpi.h | 2 +- include/efi_loader.h | 18 ++++++ lib/efi_loader/efi_gop.c | 16 +++++ lib/efi_loader/efi_runtime.c | 101 ++++++++++++++++++++++++++---- 9 files changed, 192 insertions(+), 22 deletions(-) -- 1.8.5.6
