The current implementation of the bootloader specification depends on the
hardware name and the name of the device in /dev to match. As the default
hardware name is mciX and the device name is diskY the bootloader spec
cannot be used as is.
This patch implements a way to overwrite the device name similar to what is
possible for the imx-esdhc driver.

Drivers currently cannot implement explicit cache handling and rely on
running the same code before and after mmu_initcall() without crashing.
Depending on the chosen config options, the cache functions are not yet
setup and using them early on ends in a null pointer dereference.
The RPi's mailbox driver is such a case; it requires cache handling once
the MMU is fully set up and yet the RPi setup needs to use the driver to
get the memory size before mem_initcall() and hence mmu_initcall().
Fix this by checking the cache_fns pointer before dereferencing it.

This introduces some new environment variable helpers and updates
the existing ones. Newly introduced are:
getenv_bool: read a bool variable
getenv_ul: read an unsigned long variable
getenev_uint: read an unsigned int variable
getenv_nonempty: like normal getenv, but does return NULL instead of an
empty string
All new helpers take a pointer to the value. This value is only modified
when the variable exists. This allows the following programming scheme:
unsigned int myvalue = sanedefault;
getenv_uint("myvalue", &myvalue);
So without checking the return value myvalue contains the best possible
value.
getenv_ull is updated to this scheme.

omap_save_bootinfo derefences the argument passed to barebox without
checking it for validity. This breaks 2nd stage booting where r0
is undefined. The best we can do is to check whether the pointer is
somewhere in SRAM and is word aligned. This at least makes sure that
we do not oops. This introduces SoC specific xxx_save_bootinfo variants
since the SRAM addresses/sizes differ between SoCs.
