trini: Disable CONFIG_SPL_USE_ARCH_MEMSET on orangepi_2
Signed-off-by: NTom Rini <trini@konsulko.com>

Add separate enable/disable controls for driver-model serial. While this
is generally enabled in SPL it may not be in TPL, since serial output can
be obtained with the debug UART with minimal code size.
Signed-off-by: NSimon Glass <sjg@chromium.org>

Since TPL often needs to be very very small it may not make sense to
enable driver model. Add an option for this.

This changes brings the 'rock' board under the TPL limit with gcc 4.9.

At present we have SPL_ which can be used in Makefiles to select between
normal and SPL CONFIGs like this:

    obj-$(CONFIG_$(SPL_)DM)		+= core/

When TPL is being built, SPL_ has the value 'SPL' which is generally a
good idea since they tend to follow each other. But in extreme situations
we may want to distinugish between SPL and TPL. For example we may not
want to enable CONFIG_DM with TPL.

Add a new SPL_TPL_ variable which is set to either empty (for U-Boot
proper), 'SPL' or 'TPL'. This may prove useful with TPL-specific options.

Move the ugly #ifdefs inside the reserve_video() function so we can

The arch-specific details of the cache being off are best handled inside
the reserve_mmu(). This cleans up the init sequence a little.

CONFIG_ALT_LB_ADDR is really a detail of how this logbuffer is allocated

All archs put U-Boot at the bottom of the relocated region. Xtensa does
not, but perhaps not for any good reason. Adjust it to see if things
still work OK.
Signed-off-by: NSimon Glass <sjg@chromium.org>

At present we cannot use this function as an init sequence call without a
wrapper, since it returns the RAM size. Adjust it to set the RAM size in
global_data instead, and return 0 on success.

Clean up board_f sequence a little
This series tries to remove #ifdefs from the board_f init sequence. It
gets as far as I2C and then we need to discuss whether we can start to
remove the old I2C framework.

I think that ideally each entry in the init sequence should be enabled by
at most one CONFIG, which is in Kconfig and is not arch-specific.

At present we misuse print_cpuinfo() do so CPU init on x86. This is done
because it is the next available call after the console is enabled. But
several arches use checkcpu() instead. Despite the horrible name (which
we can fix), it seems a better choice.

Adjust the various x86 CPU implementations to move their init code into
checkcpu() and use print_cpuinfo() only for printing CPU info.

While x86 is the only user and this could in principle be moved to
arch_cpu_init() there is some justification for this being a separate
call. It provides a way to handle init which is not CPU-specific, but
must happen before the CPU can be set up.

Rename the function to be more generic.

When this board was switched to using more DM drivers we didn't disable
the legacy PCA953X driver.  This in turn learn to a build time warning
about implicit functions as i2c.h would not say anything about
'i2c_read' nor 'i2c_write'.  But this was not a fatal error as none of
the legacy driver would be linked in either.
