* da850evm: fix NAND WSTROBE and TA timingsBen Gardiner2011-05-11-2/+2
| | | | | | | | | | | | | | | | The current NAND timings, introduced in commit a3f88293ddd13facd734769c1664d35ab4ed681f da850evm: setup the NAND flash timings , incorrectly set WSTROBE and TA to 0. A more recent inspection of the values set by the Linux kernel indicates that these should be set to 1. Set the WSTROBE and TA field of the EMIFA cycle-count timings configuration to 1 to match the values set by linux.

* da850: Add RMII support for EMACSudhakar Rajashekhara2010-11-30-4/+122
| | | | | | | | | | | | | | | | | | | | | | | This patch is a port of the work by Sudhakar Rajeshekhara in commit ab3effbcad8851cc65dc5241a01c064d2030a3b2 of git://arago-project.org/git/people/sandeep/u-boot-davinci.git. The da850 UI board has on it an RMII PHY which can be used if the MDC line to the MII PHY on the baseboard is disabled and the RMII PHY is enabled by configuring the values of some GPIO pins on the IO expander of the UI board. This patch implements disabling that line via GPIO2[6], configuring the UI board's IO expander and setting only the pinmux settings that are needed for RMII operation. Tested on da850evm by adding a define for CONFIG_DRIVER_TI_EMAC_USE_RMII.

* Add board support for hawkboardSughosh Ganu2010-11-30-0/+228
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch adds basic board support for TI's OMAP-L138 based Hawkboard. This board is pretty similar to the da850 EVM. Support for nand and network access is added in this version. The following bootup procedure is used. At reset, the Rom Boot Loader(RBL), initialises the ddr and the nand controllers and copies the second stage bootloader(nand_spl) to RAM. The secondary bootloader then copies u-boot from a predefined location in the nand flash to the RAM, and passes control to the u-boot image. Three config options are supported * hawkboard_config - Used to create the u-boot.bin. Tftp the u-boot.bin image to the RAM from u-boot, and flash to the nand flash at address 0xe0000. * hawkboard_nand_config - Used to generate the secondary bootloader(nand_spl) image. This creates an elf file u-boot-spl under nand_spl/. Create an AIS signed image using this file, and flash it to the nand flash at address 0x20000. The ais file should fit in one block. * hawkboard_uart_config - This is same as the first image, but with the TEXT_BASE as expected by the RBL(0xc1080000).

* DA850 EVM: passing maximum clock rate information to kernelSekhar Nori2010-11-19-0/+33
| | | | | | | | | | | | | | | | | | | | 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 <nsekhar@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <sebastien.carlier@gmail.com>

| | | | | | | | | | | | 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.

* da850evm: basic MII EMAC supportBen Gardiner2010-10-17-0/+49
| | | | | | | | | | | | | | | | 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 timingsBen Gardiner2010-10-17-0/+18
| | | | | | | | | | | | The default NAND flash timings are very conservative. This patch assigns the timings reccomended in the recent linux kernel patch [1] from Sekhar Nori.

* da850evm : enable NAND even when not in NAND boot modeBen Gardiner2010-10-17-0/+22
| | | | | | | | | | | | | | | 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_hwaddrBen Gardiner2010-10-11-4/+8
| | | | | | | | | | | | | | | | | | | | | | 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.
