From c7de829c796978e519984df2f1c8cfcf921a39a4 Mon Sep 17 00:00:00 2001 From: wdenk Date: Tue, 19 Nov 2002 11:04:11 +0000 Subject: * Patch by Thomas Frieden, 13 Nov 2002: Add code for AmigaOne board (preliminary merge to U-Boot, still WIP) * Patch by Jon Diekema, 12 Nov 2002: - Adding URL for IEEE OUI lookup - Making the autoboot #defines dependent on CONFIG_AUTOBOOT_KEYED being defined. - In the CONFIG_EXTRA_ENV_SETTINGS #define, the root-on-initrd and root-on-nfs macros are designed to switch how the default boot method gets defined. --- tools/updater/update.c | 67 ++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 67 insertions(+) create mode 100644 tools/updater/update.c (limited to 'tools/updater/update.c') diff --git a/tools/updater/update.c b/tools/updater/update.c new file mode 100644 index 0000000000..66c6dfc30d --- /dev/null +++ b/tools/updater/update.c @@ -0,0 +1,67 @@ +#include +#include + +extern unsigned long __dummy; +void do_reset (void); +void do_updater(void); + +void _main(void) +{ + int i; + mon_printf("U-Boot Firmware Updater\n\n\n"); + mon_printf("****************************************************\n" + "* ATTENTION!!
