DA850 EVM: passing maximum clock rate information to kernel

2010-11-19T21:29:11Z

The TI DA850/OMAP-L138/AM18x EVM can be populated with devices having different maximum allowed CPU clock rating. The maximum clock the chip can support can only be determined from the label on the package (not software readable). Introduce a method to pass the maximum allowed clock rate information to kernel using ATAG_REVISION. The kernel uses this information to determine the maximum cpu clock rate reachable using cpufreq. Note that U-Boot itself does not set the CPU clock rate. The CPU clock is setup by a primary bootloader ("UBL"). The rate setup by UBL could be different from the maximum clock rate supported by the device. Signed-off-by: Sekhar Nori Signed-off-by: Sandeep Paulraj

Switch from archive libraries to partial linking

2010-11-17T20:02:18Z

Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier

Drop support for CONFIG_SYS_ARM_WITHOUT_RELOC

2010-10-29T19:39:59Z

When this define was introduced, the idea was to provide a soft migration path for ARM boards to get adapted to the new relocation support. However, other recent changes led to a different implementation (ELF relocation), where this no longer works. By now CONFIG_SYS_ARM_WITHOUT_RELOC does not only not help any more, but it actually hurts because it obfuscates the actual code by sprinkling it with lots of dead and non-working debris. So let's make a clean cut and drop CONFIG_SYS_ARM_WITHOUT_RELOC. Signed-off-by: Wolfgang Denk Tested-by: Heiko Schocher Tested-by: Reinhard Meyer

Remove config.mk for da8xxevm based boards.

Move CONFIG_SYS_TEXT_BASE to the board's config file, and remove the now unnecessary config.mk file. Signed-off-by: Sughosh Ganu Tested-by: Ben Gardiner

Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE

2010-10-18T20:07:10Z

The change is currently needed to be able to remove the board configuration scripting from the top level Makefile and replace it by a simple, table driven script. Moving this configuration setting into the "CONFIG_*" name space is also desirable because it is needed if we ever should move forward to a Kconfig driven configuration system.

schmoogie: fix build error due to removal of forceenv()

2010-10-18T19:46:37Z

commit 6d014adf dropped support for the forceenv() function, but failed to remove references to it from board/davinci/schmoogie/schmoogie.c Replace forceenv() by setenv() and set CONFIG_ENV_OVERWRITE instead in the board config file to allow overwriting the serial number.

da850evm: basic MII EMAC support

2010-10-17T18:14:55Z

The current da850evm support in u-boot/master omits any use of the davinci EMAC. This patch adds basic support for the EMAC using the MII PHY found on the baseboard of the EVM. The MAC address is read from the environment variable 'ethadd'. Note that this is different from the da850evm support in the u-boot omapl1 tree where the MAC address is read from SPI flash.

da850evm: setup the NAND flash timings

2010-10-17T18:14:47Z

The default NAND flash timings are very conservative. This patch assigns the timings reccomended in the recent linux kernel patch [1] from Sekhar Nori. The speedup, as reported in that patch, is 5.3x for reads. [1] http://www.spinics.net/lists/arm-kernel/msg100278.html Signed-off-by: Ben Gardiner CC: Sekhar Nori Signed-off-by: Sandeep Paulraj

da850evm : enable NAND even when not in NAND boot mode

2010-10-17T18:14:45Z

There is currently no NAND pinmux enabled by the da850evm board setup code. This is fine when booting from NAND since the early boot code (UBL) will setup the pinmux; however, when the boot mode is any other setting NAND is unusable when enabled in the config. This patch adds a pinmux list for NAND and enables it when NAND is enabled in the config. Tested by booting from SPI on the da850evm and verifying NAND was usable.

davinci_emac: davinci_eth_set_mac_addr to ->write_hwaddr

2010-10-12T06:07:17Z

This patch proposes to migrate the davinci_emac driver to using the eth_device->write_hwaddr function pointer as suggested by Ben Warren. All the davinci boards had the behaviour, prior to this patch, of sync'ing the environment variable enetaddr with the MAC address read from non-volatile storage on boot -- when the two locations disagreed, the environment variable value took precendence. This patch keeps the same behaviour but lets eth_initialize take care of it. This patch refactors davinci_emac setup in the boards so that the MAC address is read from non-volatile storage into the environment variable and then the environment variable value is use in eth_intialize. The only exception is the direct call to davinci_eth_set_mac_addr made by the da830evm board init which was changed into an assignment of the enetaddr field.
