From 6dd652fa4d8591a32e2707a91f4582ed13011b17 Mon Sep 17 00:00:00 2001 From: wdenk Date: Thu, 19 Jun 2003 23:40:20 +0000 Subject: Patches by Murray Jensen, 17 Jun 2003: - Hymod board database mods: add "who" field and new xilinx chip types - provide new "init_cmd_timeout()" function so code external to "common/main.c" can use the "reset_cmd_timeout()" function before entering the main loop - add DTT support for adm1021 (new file dtt/adm1021.c; config slightly different. see include/configs/hymod.h for an example (requires CONFIG_DTT_ADM1021, CONFIG_DTT_SENSORS, and CFG_DTT_ADM1021 defined) - add new "eeprom_probe()" function which has similar args and behaves in a similar way to "eeprom_read()" etc. - add 8260 FCC ethernet loopback code (new "eth_loopback_test()" function which is enabled by defining CONFIG_ETHER_LOOPBACK_TEST) - gdbtools copyright update - ensure that set_msr() executes the "sync" and "isync" instructions after the "mtmsr" instruction in cpu/mpc8260/interrupts.c - 8260 I/O ports fix: Open Drain should be set last when configuring - add SIU IRQ defines for 8260 - allow LDSCRIPT override and OBJCFLAGS initialization: change to config.mk to allow board configurations to override the GNU linker script, selected via the LDSCRIPT, make variable, and to give an initial value to the OBJCFLAGS make variable - 8260 i2c enhancement: o correctly extends the timeout depending on the size of all queued messages for both transmit and receive o will not continue with receive if transmit times out o ensures that the error callback is done for all queued tx and rx messages o correctly detects both tx and rx timeouts, only delivers one to the callback, and does not overwrite an earlier error o logic in i2c_probe now correct - add "vprintf()" function so that "panic()" function can be technically correct - many Hymod board changes --- board/hymod/flash.c | 509 ++++++++++++++-------------------------------------- 1 file changed, 135 insertions(+), 374 deletions(-) (limited to 'board/hymod/flash.c') diff --git a/board/hymod/flash.c b/board/hymod/flash.c index 0a09b4a70e..7d1ae30e48 100644 --- a/board/hymod/flash.c +++ b/board/hymod/flash.c @@ -20,7 +20,7 @@ * Foundation, Inc., 59 Temple Place, Suite 330, Boston, * MA 02111-1307 USA * - * Hacked for the Hymod board by Murray.Jensen@cmst.csiro.au, 20-Oct-00 + * Hacked for the Hymod board by Murray.Jensen@csiro.au, 20-Oct-00 */ #include @@ -35,235 +35,155 @@ flash_info_t flash_info[CFG_MAX_FLASH_BANKS]; /* info for FLASH chips */ #define FLAG_PROTECT_SET 0x01 #define FLAG_PROTECT_CLEAR 0x02 -/*----------------------------------------------------------------------- - * Functions - */ -#if 0 -static ulong flash_get_size (vu_long *addr, flash_info_t *info); -static void flash_get_offsets (ulong base, flash_info_t *info); -#endif -static int write_word (flash_info_t *info, ulong dest, ulong data); - /*----------------------------------------------------------------------- */ /* - * probe for the existence of flash at bank word address "addr" - * 0 = yes, 1 = bad Manufacturer's Id, 2 = bad Device Id + * probe for flash bank at address "base" and store info about it + * in the flash_info entry "fip".
