cppcheck cleanup: fix nullPointer errors

2014-11-07T21:27:07+00:00

There are a number of places where U-Boot intentionally and legally
accesses physical address 0x0000, for example when installing
exception vectors on systems where these are located in low memory.

Add "cppcheck-suppress nullPointer" comments to silence cppcheck
where this is intentional and legal.

blackfin: Correct early serial mess output in BYPASS boot mode.

2013-05-13T07:47:24+00:00

The early serial should not be configured again in initcode() for BYPASS
boot mode and in start() for the other LDR boot modes.

In BYPASS boot mode, the start up code is located in Nor flash address other
than the DRAM address defined in link script. The code embedded string can't
be addressed by its compile time symbol. Calculate it according to the flash
offset.

blackfin: Set correct early debug serial baudrate.

2013-05-13T07:47:24+00:00

Calculate the early uart clock from the system clock registers set by
the bootrom other than the predefine uboot clock macros.

Split the early baudrate setting function and the normal baudrate
setting one.

Blackfin: adjust asm constraints with NMI workaround

2013-05-13T07:47:24+00:00

Newer gcc versions will sometimes use a Preg when "r" constraints, but
that'll fail if we use an Ireg in the assignment.  So force the code
to always use a Dreg.

This also fixes early boot crashes for older Blackfin parts when compiled
with gcc-4.5.  This version ends up selecting the same register for the
input and output variables which corrupts the output assignment triggering
an exception.
	P2 = 0xffe02008;	/* EVT2 */
	R0 = RETS;
	CALL 1f;
	RTN;
1:	P2 = RETS;	<-- BAD
	RETS = R0;
	[P2] = P2;	<-- BAD
