[U-Boot] newbie questions regarding some config options.
by Christopher Harvey 22 Aug '14

22 Aug '14

As per the README file: Subscribe to u-boot mailing list; if (clueless) email("Hi, I am new to U-Boot, how do I get started?"); I'm messing around with uboot and QEMU (qemu-system-arm -M realview-pbx-a9 -kernel u-boot.bin), things are going pretty well in the sense that I'm not having too much trouble reading most of the code and creating a new board. I have some questions that I can't figure out by reading the code. What is the CONFIG_SYS_TEXT_BASE variable and how can I figure out what it should be? I randomly set it to 0x0...then tried to debug u-boot under qemu, but when stepping in the start.S file it was instantly clear that it wasn't really working because gdb said the code ran right though the _start: b reset instruction and qemu eventually crashed with the following output: qemu: fatal: Trying to execute code outside RAM or ROM at 0xfeb70cdc R00=00000000 R01=ffff0000 R02=00000000 R03=000108ac R04=ffff0000 R05=ffbedf70 R06=ffff0000 R07=00000010 R08=00001000 R09=ffff0000 R10=000108ac R11=00000000 R12=00001078 R13=ffbedf60 R14=00000960 R15=feb70cdc PSR=600001d3 -ZC- A svc32 Aborted Apart from that everything is pretty clear to me, but I want to make sure I'm getting this points right: Is the environment the set of variables that can be modified with setenv? How can I determine the "size of the environment"? Is it the number of characters including variable names? Also, is there anything special I need to do with gdb to get it to follow relocating code? thanks, -Chris

[U-Boot] [PATCH] OpenRD: relocate environment to 640kB
by Sascha Silbe 14 Aug '14

14 Aug '14

U-Boot has become slightly larger than where the environment sector was previously located. Saving the environment would brick the device. Relocate the environment to where it is with the stock (i.e. Marvell USP) U-Boot version. That should give plenty of room for U-Boot to grow, including local customisations. This obviously breaks compatibility with previous mainline versions of U-Boot. Users will need to back up the environment before an update and restore it afterwards, or manually copy it to the new address before the update.

[U-Boot] [PATCH v2] gpio: spear_gpio: Fix gpio_set_value() implementation
by Axel Lin 04 Jul '14

04 Jul '14

In current gpio_set_value() implementation, it always sets the gpio control bit no matter the value argument is 0 or 1. Thus the GPIOs never set to low. This patch fixes this bug. The address bus is used as a mask on read/write operations, so that independent software drivers can set their GPIO bits without affecting any other pins in a single write operation. Thus we don't need a read-modify-write to update the register.

[U-Boot] [PATCH] ARM: fdt support: Add usbethaddr as an acceptable MAC
by Dan Murphy 19 Jun '14

19 Jun '14

A board that has a USB ethernet device only may set the usbetheraddr and not the ethaddr. ethaddr will be the default MAC address that is chosen and if that is not populated then the usbethaddr is looked at. If neither are set then then device tree blob is not modified.

[U-Boot] [PATCH] Separate EBV Socrates board from Altera Cyclone 5 board
by Pavel Machek 05 Jun '14

05 Jun '14

Altera Cyclone 5 board is very different board (big, rectangular, expensive) than EBV Socrates (small, circular, cheap) board. Different parts are used there, too, but same configuration of u-boot works on both. Nevertheless, printing wrong name confuses users. Therefore this splits the configuration so that u-boot knows they are different. So far it is only used for correcting the puts, but there may be other uses in future.

[U-Boot] [PATCH 0/9] ARMv7: add PSCI support to u-boot
by Marc Zyngier 04 Jun '14

04 Jun '14

PSCI is an ARM standard that provides a generic interface that supervisory software can use to manage power in the following situations: - Core idle management - CPU hotplug - big.LITTLE migration models - System shutdown and reset It basically allows the kernel to offload these tasks to the firmware, and rely on common kernel side code. More importantly, it gives a way to ensure that CPUs enter the kernel at the appropriate exception level (ie HYP mode, to allow the use of the virtualization extensions), even across events like CPUs being powered off/on or suspended. The main idea here is to reuse some of the existing u-boot code to create a separate blob that can live in SRAM (or a reserved page of memory), containing a secure monitor that will implement the PSCI operations. This code will still be alive when u-boot is long gone, hence the need for a piece of memory that will not be touched by the OS. This patch series contains 3 parts: - the first four patches are just bug fixes - the next three contain the generic PSCI code and build infrastructure - the last two implement the CPU_ON method of the Allwinner A20 (aka sun7i). I realize the A20 u-boot code is not upstream yet (BTW is anyone actively working on that?), but hopefully that should give a good idea of how things are structured so far. The patches are against a merge of u-boot mainline and the sunxi tree as of ten days ago. As for using this code, it goes like this: sun7i# ext2load mmc 0:1 0x40000000 /boot/sunxi-psci.bin 908 bytes read in 18 ms (48.8 KiB/s) sun7i# cp 0x40000000 0x4000 0x1000 sun7i# ext2load mmc 0:1 40008000 /boot/zImage 3415087 bytes read in 184 ms (17.7 MiB/s) sun7i# setenv bootargs console=ttyS0,115200 earlyprintk root=/dev/nfs nfsroot=10.1.203.35:/export/roots/bobby-brown,tcp,v3 rw ip=dhcp sun7i# bootz 40008000 The kernel now boots in HYP mode, finds its secondary CPU without any additional SMP code, and runs KVM out of the box. Hopefully, the Xen/ARM guys can do the same fairly easily. I'm wildly cross-posting this patch series, including to lists I'm not subscribed to. Please keep me on Cc for any comment you may have.
