Revision History
Date Who Comment
________ ___ _____________________________________________________________
09/17/01 cds initial version
06/25/02 cds incorporated boot block reading/writing for device usb config
info
06/27/02 cds - overrode media_set_read/write/erase_addr() to calculate
chip/zone info from g_addr_zone
- exported g_nand_num_chips and g_nand_zones_per_chip for
tracking nand drive geometry
09/05/02 cds removed unused constants in nand flash geometry section
(max_chips and bytes_per_page)
11/21/02 ds Modified nand_write_boot_flush to suit nand_int implementation. The prototype for nand_in_select_chip is
added here.
