* davinci_emac: davinci_eth_set_mac_addr to ->write_hwaddrBen Gardiner2010-10-11-33/+10
| | | | | | | | | | | | | | | | | | | | | | 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.

* da8xx: fixup ARM relocation supportBen Gardiner2010-09-19-0/+17
| | | | | | | | | | | | | | | | | | | | | Split the existing dram_init for da8xx when ARM reloc is enabled, like the changes to arch/arm/cpu/arm926ejs/orion5x/dram.c in 0f234d263b17ccf1b8fd776eb8c15b7cdb27a887 by Heiko Schocher <hs@denx.de>. Without these changes gd->ram_size is '0' which leads to incorrect relocation when CONFIG_SYS_ARM_WITHOUT_RELOC is defined and the board does not boot. We use get_ram_size to dynamically calculate the available RAM because it runs on different board version with different ram, as suggested by Heiko in private communication. Tested on a da850evm with 128M of DDR2 installed; with both CONFIG_SYS_ARM_WITHOUT_RELOC defined and undefined.

* Davinci: Table driven pinmux configurationNick Thompson2010-01-04-0/+44
| | | | | | | | | | | | | | | Davinci: Table driven pinmux configuration Add code to allow pinmux_config tables to be grouped and configured as a single resource. This removes multiple calls to the pinmux configuration code from board_init and allows pinmuxes to be individually configured and added by data manipulation only. All related #ifdefs can the be removed from board_init code and since the compiler optimises away statics, #ifdefs can be reduced in the data definitions as well.

* TI Davinci: add a pin multiplexer configuration APINick Thompson2009-11-27-1/+59
| | | | | | | | Creates a method allowing pin settings to be logically grouped into data structure arrays and provides an API to configure the pinmux settings to enable the relevant pin functions. Signed-off-by: Nick Thompson <nick.thompson@gefanuc.com>
* Switched davinci_emac Ethernet driver to use newer APIBen Warren2009-06-15-1/+0
| | | | | | | | Added CONFIG_NET_MULTI to all Davinci boards Removed all calls to Davinci network driver from board code Added cpu_eth_init() to cpu/arm926ejs/cpu.c Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
* davinci: display correct clock infoDavid Brownell2009-06-12-13/+1
| | | | | | | | | | | | Move the clock-rate dumping code into the cpu/.../davinci area where it should have been, enabled by CONFIG_DISPLAY_CPUINFO, updating the format and showing the DSP clock (where relevant). Switch boards to use the cpuinfo() hook for this stuff. Remove a few now-obsolete PLL #defines. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* arm: timer and interrupt init reworkJean-Christophe PLAGNIOL-VILLARD2009-06-12-1/+0
| | | | | | | | | | | | | | actually the timer init use the interrupt_init as init callback which make the interrupt and timer implementation difficult to follow so now rename it as int timer_init(void) and use interrupt_init for interrupt btw also remane the corresponding file to the functionnality implemented as ixp arch implement two timer - one based on interrupt - so all the timer related code is moved to timer.c Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>
* davinci: move psc support board-->cpuDavid Brownell2009-06-12-215/+1
| | | | | | | | Move DaVinci PSC support from board/* to cpu/* where it belongs. The PSC module manages clocks and resets for all DaVinci-family SoCs, and isn't at all board-specific. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* DaVinci Ethernet cleanupDavid Brownell2009-06-12-19/+15
| | | | | | | | | | | | | | | | Chips without the EMAC controller won't need the utilities it uses to read an Ethernet address from EEPROM; so don't include them needlessly. Use is_valid_ether() to validate the address from EEPROM. All-zero addresses aren't the only invalid addresses. A fully erased EEPROM returns all-ones, also invalid... Switch those Ethernet utilities to use "%pM" for printing MAC addresses; and not say ROM when they mean EEPROM.

* ARM DaVinci: Add common peripherals and modules enable functions.Hugo Villeneuve2009-02-22-0/+68
| | | | | | | | | | Taken all the duplicated code for enabling common modules and apply software workarounds from the board specific code into common functions. Also added comments explaining the workarounds (from TI errata documents) and replaced some numerical bit numbers with more meaningful defines.
