7444992999 soc: bios: fix windows build 
The BIOS builds just fine on Windows, but afterwards tries to run
`chmod`.  This command does not exist on Windows, and is unnecessary.

Add a conditional guard to prevent this command from running on Windows.

75e7f9505a BIOS: Flashboot without main ram 
Modified flashboot() to skip copy to main ram if there is no main
ram, and instead execute in place out of SPI flash.  (For this to
work the linker .ld will also need to redirect references to be
inside the SPI flash mapping.)

97f381baa6 BIOS: allow BIOS to specify TFTP server port 
Swaps hard coded PORT_OUT in tftp.c for parameter on the tftp_get()
and tftp_put() functions.  Allow TFTP_SERVER_PORT used by BIOS to be
set at compile time from compiler defines.

21ad435def Include the ethernet related header files conditionally 
Only including those header files in the litex firmware is the first step to
move the firmware parts of liteeth to the liteeth tree.

782711e5a9 bios/sdram: make read leveling robust for KUS SDRAM 
Increases the initial delay step into the valid read window as
with the original delay I was not getting out of the noisy
transition window, as evidenced by seeing read delay windows
of only 8 LSB ~10% of the time, leading to failing memory
tests
