- ProxyDHCP allows a second DHCP server to exist alongside your main
DHCP server and supply additional BOOTP related options
- When u-boot sends out a DHCP request, the real DHCP server will
respond with a normal response containing the new client IP address
while simultaneously the ProxyDHCP server will respond with a blank
client IP address and a `bootfile` option
- This patch adds CONFIG_SERVERIP_FROM_PROXYDHCP (default false) to
enable this behavior and CONFIG_SERVERIP_FROM_PROXYDHCP_DELAY_MS
(default 100) which tells u-boot to wait additional time after
receiving the main DHCP response to give the ProxyDHCP response time
to arrive
- The PXE spec for ProxyDHCP is more complicated than the solution
added here as diagramed on page 16:
http://www.pix.net/software/pxeboot/archive/pxespec.pdf:
```
DHCP Discover will be retried four times. The four timeouts are 4, 8, 16
and 32 seconds respectively. If a DHCPOFFER is received without an Option
timeouts in an attempt to receive a PXE response.
```
- Adding a simple delay worked for my purposes but let me know if a
more robust solution is required

- Update FIT examples to avoid kernel zImage relocation before decompression
Update kernel load address for FIT examples to avoid relocation:
- Kernel example uses Image.gz with U-Boot gzip decompression
at final kernel location 0x0xC0008000.
- Copro example loads zImage at a correct location (0xC4000000),
to avoid zImage relocation before decompression by kernel code.
An other solution to avoid zImage relocation is to align
the kernel load and entry address with the real location in FIT
(the relocation of zImage is skipped in U-Boot bootm command for
identical address) but it is less flexible because this offset
depends on FIT content:
For example:
## Loading kernel from FIT Image at c2000000 ...
