9868b14263 blackfin: gpio: Use proper mask for comparing function
The function return from P_FUNCT2MUX(per) takes 2 bits, however
for BF537_FAMILY with offset != 1 the function is 1 bit.

Also has small refactor for better readability.
In portmux_setup(), it looks odd having "muxreg &= ~(3 << 1);"
while in current code we do muxreg |= (function << offset);.

da34aae5fb bfin: Move gpio support for bf54x and bf60x into the generic driver folder.
The gpio spec for bf54x and bf60x differ a lot from the old gpio driver for bf5xx.
A lot of machine macros are used to accomodate both code in one gpio driver.
This patch split the old gpio driver and move new gpio2 support to the generic
gpio driver folder.

- To enable gpio2 driver, macro CONFIG_ADI_GPIO2 should be defined in the board's
config header file.
- The gpio2 driver supports bf54x, bf60x and future ADI processors, while the
older gpio driver supports bf50x, bf51x, bf52x, bf53x and bf561.
- All blackfin specific gpio function names are replaced by the generic gpio APIs.

2e2ed3f4ff Blackfin: adjust asm constraints with NMI workaround
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.

ef123c5253 Refactor linker-generated arrays
Refactor linker-generated array code so that symbols
which were previously linker-generated are now compiler-
generated. This causes relocation records of type
R_ARM_ABS32 to become R_ARM_RELATIVE, which makes
code which uses LGA able to run before relocation as
well as after.

Note: this affects more than ARM targets, as linker-
lists span possibly all target architectures, notably
PowerPC.

41651cab97 serial: bfin: Flip the jtag serial console to CONFIG_SERIAL_MULTI
Rework the emulation of serial console via JTAG from simple ad-hoc
implementation of serial port routines to CONFIG_SERIAL_MULTI and
enable CONFIG_SERIAL_MULTI unconditionally for blackfin.

In order for the JTAG serial console to take precedence over all
other serial ports available in system, implement override for
default_serial_console call returning this JTAG serial console.

This brings in a bit of a growth of size, but eventually will allow
us to unconditionally enable CONFIG_SERIAL_MULTI throughout the whole
U-Boot and maintain only one serial subsystem.
