-
- Enable printing of hash marks during FPGA
- configuration.

- indicated a CRC error).
-
- CFG_FPGA_WAIT_INIT
-

- after PROB_B has been deasserted during a Virtex II
- FPGA configuration sequence. The default time is 500 mS.

of the backslashes before semicolons and special
symbols.

the environment like the autoscript function or the
boot command first.

CONFIG_HAS_DATAFLASH
Defining this option enables DataFlash features and
allows to read/write in Dataflash via the standard
commands cp, md...
-- Show boot progress
+- SystemACE Support:
+ CONFIG_SYSTEMACE
+
+ Adding this option adds support for Xilinx SystemACE
+ chips attached via some sort of local bus. The address
+ of the chip must alsh be defined in the
+ CFG_SYSTEMACE_BASE macro. For example:
+
+ #define CONFIG_SYSTEMACE
+ #define CFG_SYSTEMACE_BASE 0xf0000000
+
+ When SystemACE support is added, the "ace" device type
+ becomes available to the fat commands, i.e. fatls.

Modem Support:
Enables debugging stuff (char screen[1024], dbg())
for modem support. Useful only with BDI2000.
+- Interrupt support (PPC):
+
+ There are common interrupt_init() and timer_interrupt()
+ for all PPC archs. interrupt_init() calls interrupt_init_cpu()
+ for cpu specific initialization. interrupt_init_cpu()
+ should set decrementer_count to appropriate value. If
+ cpu resets decrementer automatically after interrupt
+ (ppc4xx) it should set decrementer_count to zero.
+ timer_interrupt() calls timer_interrupt_cpu() for cpu
+ specific handling. If board has watchdog / status_led
+ / other_activity_monitor it works automatically from
+ general timer_interrupt().
