[U-Boot] [PATCHv2] powerpc: Minimal private libgcc to build on Debian
by Kyle Moffett 14 Apr '11

14 Apr '11

Standard Debian powerpc and powerpcspe systems only include hard-float libgcc in their native compilers, which causes scary build warnings when building U-Boot. Debian and other PowerPC-supporting distributions used to provide libgcc and other libraries in a "nof" (soft-float) form in the "multilib" packages. As they were completely unused by the distribution and therefore tended to be very buggy it was decided to save some time on the part of the maintainers and build-servers by removing them. Admittedly, right now the linker warnings do not indicate any problems, as the included routines do not use any floating point at all. The concern is that if floating-point code were ever added it might cause hard-float code to be unexpectedly included in U-Boot without generating a hard error. This would cause unexplained crashes or indeterminate results at runtime. The easiest way to resolve this is to borrow the routines that U-Boot needs from the Linux kernel, which has the same issue. Specifically, the routines are: _ashldi3(), _ashrdi3(), and _lshrdi3(). They were borrowed from arch/powerpc/kernel/misc_32.S as of v2.6.38-rc5, commit 85e2efbb1db9a18d218006706d6e4fbeb0216213, and are GPLv2+. The Makefile framework was copied from the U-Boot ARM port.

1. ftpmu010.h: fix and add definitions Enhanced for more features and asm related support according to datasheet. Note: - FTPMU010_PDLLCR0_HCLKOUTDIS is "incorrect" in datasheet. - FTPMU010_PDLLCR0_DLLFRANG is only 1 bit at bit #19. (not 20-19) - FTPMU010_PDLLCR0_HCLKOUTDIS is 4 bits at bit #20. (not 24-21) 2. ftpmu010.c: enhance features and fix relocation - The following functions is added for pmu features. ftpmu010_mfpsr_select_dev() ftpmu010_sdramhtc_set() - This patch also fix the declare statement for relocation.

[U-Boot] [PATCH v2] I2C: OMAP: detect more devices when probing an i2c bus
by Nick Thompson 14 Apr '11

14 Apr '11

The omap24xx driver only seems to support devices that have a single subaddress byte. With these types of devices, the first access in a bus transaction is usually a write (writes the subaddress) followed by either a read or write to access the devices registers. Many such devices will respond to a read as the first access, but there are at least some that will NACK such a read. (e.g. ADV7180.) The probe function attempts to detect a devices ACK to a read access only and fails to find devices that NACK a read. This commit modifies the probe function to start a write instead. This detects devices that respond to reads (since they must also respond to writes) as well as those that only respond to writes. The bus is immediately set to idle after a (N)ACK avoiding actually writing anything to the device. Signed-off-by: Nick Thompson <nick.thompson(a)ge.com> --- Tested on OMAP3530 with an ADV7180 video ADC. Detection of a device takes the same time as failing to find a device, so the probe is slightly faster.

[U-Boot] RFC: How use same interface between arm926ejs/at91 and arm920t/at91
by Andreas Bießmann 14 Apr '11

14 Apr '11

Dear Reinhard Meyer, I try to remove deprecated at91rm9200_usart driver for 2011.06 release (and switch to atmel_usart for at91rm9200 devices). This require the get_usart_clk_rate() which in turn requires get_mck_clk_rate() interface. This interface is currently implemented in a/a/c/arm926ejs/at91/clock.c and requires at91_clock_init() in the same file to run first. This implementation currently in u-boot is already prepared for at91rm9200, I could just include these files from arm926ejs in my arm920t build files and can use the interface for atmel_usart driver (my current test case copies these files to arm920t). So my question is how should we handle this? I see three options here: a) include necessary files from arm926ejs in am920t build (maybe with some extra arm920t related defines in ar926ejs) b) copy current arm926ejs files to arm920t (and maybe clean them up to only include the relevant stuff) c) build an a/a/lib/at91, copy the common part to that 'at91 library' and implement the architecture specific part in arm920t and arm926ejs respectively. regards Andreas Bießmann

[U-Boot] fw_printenv & fw_setenv for NAND partition
by Amarendra Reddy 14 Apr '11

14 Apr '11

Hi All, Thanks in Advance. Please clarify the following. We are using ARM9 core Samsung controller with NAND Flash & U-Boot bootloader. è There is a partition mtd1 in NAND containing the environment variables mtd1: 00080000 00020000 "NVRAM" è The size of mtd1 is 512 KB. Basically mtd1 contains 4 Blocks. Each Block is 128KB. è The size of environment variables in 8KB. è But this mtd1 has 4 redundant copies of environment variables . è Block1 contains first copy of environment variables. This occupies only 8KB of Block1. è Similarly Block2, Block3, Block4 each contain a copy of environment variables. I am planning to use fw_printenv & fw_setenv in Linux to access U-Boot variables. Question: Does the below fw_env.config configuration hold good ? fw_env.config # Configuration file for fw_(printenv/saveenv) utility. # Up to two entries are valid, in this case the redundand # environment sector is assumed present. # MTD device name Device offset Env. size Flash sector size /dev/mtd1 0x00000 0x02000 0x20000 /dev/mtd1 0x20000 0x02000 0x20000 /dev/mtd1 0x40000 0x02000 0x20000 /dev/mtd1 0x60000 0x02000 0x20000 Extra Info: MTD1 starts at 768 KiB as shown below. CC9M2443 # flpart Nr | Name | Start | Size | Type | FS | Flags ---------------------------------------------------------------------------- 0 | U-Boot | 0 | 768 KiB | U-Boot | | fixed 1 | NVRAM | 768 KiB | 512 KiB | NVRAM | | fixed 2 | Kernel | 1280 KiB | 3 MiB | Linux-Kernel | | 3 | Rootfs-Jffs2 | 4352 KiB | 30 MiB | Filesystem | JFFS2 | rootfs Thanks & Regards Amarendra Reddy Larsen & Toubro Limited www.larsentoubro.com This Email may contain confidential or privileged information for the intended recipient (s) If you are not the intended recipient, please do not use or disseminate the information, notify the sender and delete it from your system.
