[U-Boot] [PATCH 2/2] ARM: OMAP4/5: Remove dead code against CONFIG_SYS_ENABLE_PADS_ALL
by Jassi Brar 24 Jan '14

24 Jan '14

The commit f3f98bb0 : "ARM: OMAP4/5: Do not configure non essential pads, clocks, dplls" removed the config option aimed towards moving that stuff into kernel, which renders some code unreachable. Remove that code.

[U-Boot] [PATCH 1/2] ARM: OMAP4/5: Remove dead code against CONFIG_SYS_CLOCKS_ENABLE_ALL
by Jassi Brar 24 Jan '14

24 Jan '14

The commit f3f98bb0 : "ARM: OMAP4/5: Do not configure non essential pads, clocks, dplls" removed the config option aimed towards moving that stuff into kernel, which renders some code unreachable. Remove that code. Signed-off-by: Jassi Brar <jaswinder.singh(a)linaro.org> --- Hi, The commit f3f98bb0 seems to suggest we want to move these settings into the kernel, but perhaps we should also evaluate the option of making these inits fully board specific but in u-boot?

Background, two adjacent descriptors as be on one cache line may be owned by different entities (host cpu / network ip). Yes, this is a problem and I can't think of a clean solution.

Yes, I know that. The descriptors are 16 bytes and they need to be contiguous in memory PS: I have not added the list but I strongly feel that this mail should also go to the uboot list -Vipin > With kind regards, greetings, Frank. > >

Nowdays, there are plenty of mmc driver in uboot adopt the sd standard host design, aka as sdhci. It is better to centralize the common logic together to better maintenance.

[U-Boot] bootm does not work if netconsole is enabled
by Michael Walle 21 Sep '13

21 Sep '13

Hi Joe, Hi Tom, If i have the netconsole enabled i cannot boot linux using the bootm command. This bug exists at least in 2013.01.01 and 2013.04-rc2 :/ Here is the output of the serial console of a successful startup: ## Booting kernel from Legacy Image at 00100000 ... Image Name: Linux-3.8.0-rc1-00004-g270c0a0-d Image Type: ARM Linux Kernel Image (uncompressed) Data Size: 2799632 Bytes = 2.7 MiB Load Address: 00008000 Entry Point: 00008000 Verifying Checksum ... OK ## Loading init Ramdisk from Legacy Image at 00800000 ... Image Name: Image Type: ARM Linux RAMDisk Image (uncompressed) Data Size: 636966 Bytes = 622 KiB Load Address: 00000000 Entry Point: 00000000 Verifying Checksum ... OK ## Flattened Device Tree blob at 00700000 Booting using the fdt blob at 0x00700000 Loading Kernel Image ... OK OK Loading Ramdisk to 03aad000, end 03b48826 ... OK Loading Device Tree to 03aa8000, end 03aacedd ... OK Starting kernel ... [.. more linux kernel output ..] If the netconsole is enabled, eg. "stdin = stdout = stderr = nc", i see only the following output on the netconsole and then nothing more happens: ## Booting kernel from Legacy Image at 00100000 ... Image Name: Linux-3.8.0-rc1-00004-g270c0a0-d Image Type: ARM Linux Kernel Image (uncompressed) Data Size: 2799632 Bytes = 2.7 MiB Load Address: 00008000 Entry Point: 00008000 Verifying Checksum ... OK ## Loading init Ramdisk from Legacy Image at 00800000 ... Image Name: Image Type: ARM Linux RAMDisk Image (uncompressed) Data Size: 636966 Bytes = 622 KiB Load Address: 00000000 Entry Point: 00000000 Verifying Checksum ... OK ## Flattened Device Tree blob at 00700000 Booting using the fdt blob at 0x00700000 I've tracked this down to the eth_halt() call in cmd_bootm.c:647. What is the purpose of this call? I guess the NIC should be shut down prior to booting linux. OTOH, there are still messages printed after this call, and i suppose the netconsole tries to bring the network back up. If i remove this call, everything works as expected. Anyway, i can definitely say, that the linux kernel is not starting. Eg. it is not only the output that stops working. FYI, i'm using the mvgbe driver. Let me know if i can do some more debugging or provide more information. Hopefully this will be fixed in 2013.04 :) -- Michael

[U-Boot] Possible GPL violation
by Mateusz Kulikowski 12 Sep '13

12 Sep '13

Hi, Short version: Is there anyone that can support me with enforcing GPL compliance on company that ships product with binary u-boot? Or did that in the past? Long version: Polish market is flooded with cheap DVB-T receivers (we're switching to digital tv now), android tablets etc. They're "made" (branded is probably better word) by local companies, and my guess is that most of them is violating GPL. Some time ago I've bought WIWA HD100 DVB-T receiver. I have coverage issues, so I decided to play a bit with this device, just to have fun (also to try to port Linux there). I already knew that other models made by this vendor are using u-boot, so I played a bit with HW, found serial port and: <log> Hello U-Boot U-Boot 1.1.6 (Oct 13 2011 - 00:32:14) Board: MSTAR KRNOUS (CPU Speed 552 MHz) DRAM: 64 X 0 MBytes U-Boot is running at DRAM 0x87600000 </log> I also disassembled parts of asm code (AFAIR it was mips_cache_reset, but I may be wrong). I'd love to have sources (porting Linux to unknown, closed SOC is painful without documentation, u-boot sources are very helpful), so I wrote to manufacturer and called them several times. Unfortunately they either don't understand what I'm asking for, or deliberately ignoring my requests. I can't do much myself (except for nagging them for source code), as it's not my copyrights that they're infringing. Is there a chance that you can help me or should I try using GPL-Violations mailing list? Regards, Mateusz
