fc-loadtool flash ID check: change of reset after the check logic
This change only affects those flash configurations that have ID checks
enabled. The logic for resetting the flash after the ID check has been
changed as follows:
1) If the check fails, we return without attempting to reset the flash.
2) If the check is successful, we reset the flash using the configured
method (could be AMD or Intel or Intel W30) instead of always doing an
AMD flash reset as the original code did.

/* * Our loadagent will always be loaded into Calypso targets by the on-chip * boot ROM operating in the UART download mode. The lowest IRAM address * at which we can load our code is 0x800750; somewhat lower at 0x800518 * the boot ROM downloader has a few variables which may have been intended * to be private to the boot ROM, but which are useful to us. For example, * by looking at these variables, we can see which of the two UARTs was * used to feed our code to the boot ROM, and use the same UART for * subsequent communication - without building multiple versions of our * loadagent or resorting to other ugliness. * * This header file defines the layout of the IRAM structure in question, * based on the disassembly of the boot ROM. */ #ifndef __ROMVARS_H #define __ROMVARS_H #include "types.h" struct boot_rom_vars { u8 baud_rate_code; u8 pad1[3]; u32 uart_timeout; u8 uart_id; u8 pll_config; u16 cs_ws_config; u8 clktcxo_13mhz; u8 rhea_cntl; u16 chksum_cmd; u16 chksum_accum; u16 pad2; u32 branch_addr; }; #endif /* include guard */
