2 Changes since U-Boot 1.1.1:
3 ======================================================================
5 * Patch by Stephen Williams, 11 May 2004:
6 Add flash support for ST M29W040B
7 Reduce JSE specific flash.c to remove dead code.
9 * Patch by Markus Pietrek, 04 May 2004:
10 Fix clear_bss code for ARM systems (all except s3c44b0 which

13 * Fix "ping" problem on INC-IP board. Strange problem:
14 Sometimes the store word instruction hangs while writing to one of
15 the Switch registers, but only if the next instruction is 16-byte

17 makes the problem go away.

75 various changes to KUP4 board specific files
77 * Fix minor network problem on MPC5200: need some delay between
78 resetting the PHY and sending the first packet. Implemented in a
79 "natural" way by invoking the PHY reset and initialization code
80 only once after power on vs. each time the interface is brought up.
82 * Add some limited support for low-speed devices to SL811 USB controller
83 (at least "usb reset" now passes successfully and "usb info" displays

227 - add support for a new version of an Intracom board and fix
228 various other things on others.
229 - add verify support to the crc32 command (define
230 CONFIG_CRC32_VERIFY to enable it)

234 2. shut down FEC after network transfers
236 1. A new test command was added. This is a simplified version of
237 the one in the bourne shell.
238 2. A new exit command was added which terminates the current
240 3. Fixed handing of $? (exit code of last executed command)

257 (These displays are serial and not suitable for using a normal
258 framebuffer console on them)
259 - add infrastructure needed in order to POST any DSPs in a board
260 - improve and fix various things in the MPC8xx FEC driver:
261 1. The new 87x and 88x series of processors have two FECs,
262 and the new driver supports them both.
263 2. Another change in the 87x/88x series is support for
264 the RMII (Reduced MII) interface. However numerous
265 changes are needed to make it work since the PHYs
266 are connected to the same lines. That means that
267 you have to address them correctly over the MII
269 3. We now correctly match the MII/RMII interface
270 configuration to what the PHY reports.
271 - Fix problem when readingthe MII status register. Due to the
272 internal design of many PHYs you have to read the register
273 twice. The problem is more apparent in 10Mbit mode.
274 - add new mode ".jffs2s" for reading from a NAND device: it just
275 skips over bad blocks.
276 - add networking support for VLANs (802.1q), and CDP (Cisco
278 - some minor patches / cleanup

1762 "common/main.c" can use the "reset_cmd_timeout()" function before
1763 entering the main loop
1764 - add DTT support for adm1021 (new file dtt/adm1021.c; config
1765 slightly different. see include/configs/hymod.h for an example
1766 (requires CONFIG_DTT_ADM1021, CONFIG_DTT_SENSORS, and
1767 CFG_DTT_ADM1021 defined)

1769 behaves in a similar way to "eeprom_read()" etc.

1771 function which is enabled by defining CONFIG_ETHER_LOOPBACK_TEST)

1774 after the "mtmsr" instruction in cpu/mpc8260/interrupts.c

1776 - add SIU IRQ defines for 8260
1777 - allow LDSCRIPT override and OBJCFLAGS initialization: change to
1778 config.mk to allow board configurations to override the GNU
1779 linker script, selected via the LDSCRIPT, make variable, and to
1780 give an initial value to the OBJCFLAGS make variable
1781 - 8260 i2c enhancement:
1782 o correctly extends the timeout depending on the size of all
1783 queued messages for both transmit and receive
1784 o will not continue with receive if transmit times out
1785 o ensures that the error callback is done for all queued tx
1787 o correctly detects both tx and rx timeouts, only delivers one to
1788 the callback, and does not overwrite an earlier error
1789 o logic in i2c_probe now correct
1790 - add "vprintf()" function so that "panic()" function can be
1792 - many Hymod board changes

2348 (figuration of the utility, using a config file)
2350 * Add single quote support for (old) command line parser

2435 which showed "Receiver is not ready" errors when U-Boot was
2436 processing the receive buffers slower than the network controller
2439 * Patch by Andreas Oberritter, 09 Nov 2002:
2440 Change behaviour of NetLoop(): return -1 for errors, filesize
2441 otherwise; return code 0 is valid an means no file loaded - in this
2442 case the environment still gets updated!
