1146 o correctly extends the timeout depending on the size of all
1147 queued messages for both transmit and receive
1148 o will not continue with receive if transmit times out
1149 o ensures that the error callback is done for all queued tx

1152 the callback, and does not overwrite an earlier error
1153 o logic in i2c_probe now correct

1779 Add code for AmigaOne board
1780 (preliminary merge to U-Boot, still WIP)
1782 * Patch by Jon Diekema, 12 Nov 2002:
1783 - Adding URL for IEEE OUI lookup
1784 - Making the autoboot #defines dependent on CONFIG_AUTOBOOT_KEYED
1786 - In the CONFIG_EXTRA_ENV_SETTINGS #define, the root-on-initrd and
1787 root-on-nfs macros are designed to switch how the default boot
1788 method gets defined.
1790 * Patch by Daniel Engström, 13 Nov 2002:
1791 Add support for i386 architecture and AMD SC520 board
1793 * Patch by Pierre Aubert, 12 Nov 2002:
1794 Add support for DOS filesystem and booting from DOS floppy disk
1796 * Patch by Jim Sandoz, 07 Nov 2002:
1797 Increase number of network RX buffers (PKTBUFSRX in
1798 "include/net.h") for EEPRO100 based boards (especially SP8240)
1799 which showed "Receiver is not ready" errors when U-Boot was
1800 processing the receive buffers slower than the network controller
1803 * Patch by Andreas Oberritter, 09 Nov 2002:
1804 Change behaviour of NetLoop(): return -1 for errors, filesize
1805 otherwise; return code 0 is valid an means no file loaded - in this
1806 case the environment still gets updated!
1808 * Patches by Jon Diekema, 9 Nov 2002:
1809 - improve ADC/DAC clocking on the SACSng board to align
1810 the failing edges of LRCLK and SCLK
1811 - sbc8260 configuration tweaks
1812 - add status LED support for 82xx systems
1813 - wire sspi/sspo commands into command handler; improved error
1815 - add timestamp support and alternate memory test to the
1816 SACSng configuration

1819 Add "-n" to linker options to get rid of "Not enough room for
1820 program headers" problem
1822 * Patch by David Müller, 05 Nov 2002
1823 Rename CONFIG_PLL_INPUT_FREQ to CONFIG_SYS_CLK_FREQ
1824 so we can use an already existing name
