Hans de Goede [Sat, 8 Aug 2015 15:45:18 +0000 (17:45 +0200)]
dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port

Currently the serial code assumes that there is always at least one serial
port (and panics / crashes due to null pointer dereferences when there is
none).

This makes it impossible to use u-boot on boards where there is no (debug)
serial port, because e.g. all uart pins are muxed to another function.

This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which
defaults to y (preserving existing behavior), which can be set to n on
such boards to make them work.

This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing
running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial,
and is not necessary at this moment.

ddr: altera: sdram: Make sdram_start and sdram_end into u32

Originally, both sdram_start and sdram_end were 64b values. The

is only 32b, so switching sdram_start to u32 is simple.

The sdram_end is a bit more complex, since it can actually be
set to (1 << 32) if someone really wanted to use an SoCFPGA with
4 GiB of DRAM and fixed the code around a little. But, the code
handling the protection rules internally decrements the sdram_end
variable anyway. Thus, instead of calling the code and passing in
the address of the SDRAM end, pass in the address already decremented
by one. This lets the sdram_end be 32b as well.
