+See also: http://www.vooha.com/
+
+* NVRAM setenv/printenv/savenv supported.
+* Date Command
+* Serial Console support
+* Network support
+* FLASH of kernel images is supported.
+* FLASH of U-Boot to onboard and PLCC boot region.
+* Kernel command line options from NVRAM is supported.
+* IP PNP options supported.

+
+NVRAM environment variables.
+
+use the command:
+
+setenv <attribute> <value>
+
+type "saveenv" to write to NVRAM.
+
+
+
+II. To boot from a hard drive:
+
+setenv root /dev/hda1
+
+
+III. IP options which configure the network:
+
+ipaddr=<IP ADDRESS OF MACHINE>

+IV. IP Options which configure NFS Root/Boot Support
+
+root=/dev/nfs
+serverip=<NFS SERVER IP ADDRESS>
+nfsroot=<NFS SERVER IP ADDRESS>:/boot/root-fs
+
+V. U-Boot Image Support
+
+The U-Boot boot loader assumes that after you build
+your kernel (vmlinux), you will create a U-Boot image
+using the following commands or script:
+
+#!/bin/csh
+/bin/touch vmlinux.img
+/bin/rm vmlinux.img
+set path=($TOOLBASE/bin $path)
+set path=($U_BOOT/tools $path)
+powerpc-linux-objcopy -S -O binary vmlinux vmlinux.bin
+gzip -vf vmlinux.bin
+mkimage -A ppc -O linux -T kernel -C gzip -a 0 -e 0 -n vmlinux.bin.gz -d vmlinux.bin.gz vmlinux.img
+ls -l vmlinux.img
+
+
+VI. ONBOARD FLASH Support
+
+FLASH support is provided for the onboard FLASH chip Bootrom area.
+U-Boot is loaded into either the ROM boot region of the FLASH chip,
+after first being boot-strapped from a pre-progammed AMD29F040 PLCC
+bootrom. The PLCC needs to be programmed with a ROM burner using
+AMD 29F040 ROM parts and the u-boot.bin or u-boot.hex (S-Record)
+images.
+
+The PLCC overlays this same region of flash as the onboard FLASH,
+the jumper J100 is a chip-select for which flash chip you want to
+progam. When jumper J100 is connected to pins 2-3, you boot from
+PLCC FLASH.
+
+To bringup a system, simply flash a flash an AMD29F040 PLCC
+bootrom, and put this in the PLCC socket. Move jumper J100 to
+pins 2-3 and boot from the PLCC.
+
+
+Now, while the system is running, move Jumper J100 to
+pins 1-2 and follow the procedure below to FLASH a bootrom
+(u-boot.bin) image into the onboard bootrom region (AMD29LV160DB):
+
+tftp 100000 u-boot.bin
+protect off FFF00000 FFF7FFFF
+erase FFF00000 FFF7FFFF
+cp.b 100000 FFF00000 \$(filesize)\
+
+
+Here is an example:

+
+
+B. FLASH RAMDISK REGION
+
+FLASH support is provided for an Onboard 512K RAMDISK region.
+
+TThe following commands will FLASH a bootrom (u-boot.bin) image
+into the onboard FLASH region (AMD29LV160DB 2MB FLASH):
+
+tftp 100000 u-boot.bin
+protect off FFF80000 FFFFFFFF
+erase FFF80000 FFFFFFFF
+cp.b 100000 FFF80000 \$(filesize)\
+
+
+
+C. FLASH KERNEL REGION (960KB)
+
+FLASH support is provided for the 960KB onboard FLASH1 segment.
+This allows flashing of kernel images which U-Boot can load
+and run (standalone) from the onboard FLASH chip. It also assumes
+
+The following commands will FLASH a kernel image to 0xffe10000
+
+tftp 100000 vmlinux.img
+protect off FFE10000 FFEFFFFF
+erase FFE10000 FFEFFFFF

+ * Quote from 8260 UM (10.4.2 SDRAM Power-On Initialization, 10-35):
+ *
+ * "At system reset, initialization software must set up the
+ * programmable parameters in the memory controller banks registers
+ * (ORx, BRx, P/LSDMR). After all memory parameters are configured,
+ * system software should execute the following initialization sequence
+ * for each SDRAM device.
+ *
+ * 1. Issue a PRECHARGE-ALL-BANKS command
+ * 2. Issue eight CBR REFRESH commands
+ * 3. Issue a MODE-SET command to initialize the mode register
+ *
+ * Quote from Micron MT48LC8M16A2 data sheet:
+ *
+ * "...the SDRAM requires a 100uS delay prior to issuing any
+ * command other than a COMMAND INHIBIT or NOP. Starting at some
+ * point during this 100uS period and continuing at least through
+ * the end of this period, COMMAND INHIBIT or NOP commands should
+ * be applied."
+ *
+ * "Once the 100uS delay has been satisfied with at least one COMMAND
+ * INHIBIT or NOP command having been applied, a /PRECHARGE command/
+ * should be applied. All banks must then be precharged, thereby
+ * placing the device in the all banks idle state."
+ *
+ * "Once in the idle state, /two/ AUTO REFRESH cycles must be
+ * performed. After the AUTO REFRESH cycles are complete, the
+ * SDRAM is ready for mode register programming."
+ *
+ * (/emphasis/ mine, gvb)
+ *
+ * The way I interpret this, Micron start up sequence is:
+ * 1. Issue a PRECHARGE-BANK command (initial precharge)
+ * 2. Issue a PRECHARGE-ALL-BANKS command ("all banks ... precharged")
+ * 3. Issue two (presumably, doing eight is OK) CBR REFRESH commands
+ * 4. Issue a MODE-SET command to initialize the mode register
+ *
+ * --------
+ *
+ * The initial commands are executed by setting P/LSDMR[OP] and
+ * accessing the SDRAM with a single-byte transaction."
+ *
+ * The appropriate BRx/ORx registers have already been set when we
+ * get here. The SDRAM can be accessed at the address CFG_SDRAM_BASE.
