gpio: Add driver for Altera's PIO core

2011-10-28T01:50:49+00:00

This driver may handle multiple PIO cores and thus needs to be
setup by calling the altera_pio_init() function within the early
board setup routine.

The driver comes with some extras, see below the copyleft header.

punt unused clean/distclean targets

2011-10-15T20:20:36+00:00

The top level Makefile does not do any recursion into subdirs when
cleaning, so these clean/distclean targets in random arch/board dirs
never get used.  Punt them all.

MAKEALL didn't report any errors related to this that I could see.

Handle most LDSCRIPT setting centrally

2011-04-29T22:59:47+00:00

Currently, some linker scripts are found by common code in config.mk.
Some are found using CONFIG_SYS_LDSCRIPT, but the code for that is
sometimes in arch config.mk and sometimes in board config.mk.  Some
are found using an arch-specific rule for looking in CPUDIR, etc.

Further, the powerpc config.mk rule relied on CONFIG_NAND_SPL
when it really wanted CONFIG_NAND_U_BOOT -- which covered up the fact
that not all NAND_U_BOOT builds actually wanted CPUDIR/u-boot-nand.lds.

Replace all of this -- except for a handful of boards that are actually
selecting a linker script in a unique way -- with centralized ldscript
finding.

If board code specifies LDSCRIPT, that will be used.
Otherwise, if CONFIG_SYS_LDSCRIPT is specified, that will be used.

If neither of these are specified, then the central config.mk will
check for the existence of the following, in order:

$(TOPDIR)/board/$(BOARDDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT)
$(TOPDIR)/$(CPUDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT)
$(TOPDIR)/board/$(BOARDDIR)/u-boot.lds
$(TOPDIR)/$(CPUDIR)/u-boot.lds

Some boards (sc3, cm5200, munices) provided their own u-boot.lds that
were dead code, because they were overridden by a CPUDIR u-boot.lds under
the old powerpc rules.  These boards' own u-boot.lds have bitrotted and
no longer work -- these lds files have been removed.

nios2: reset cfi flash before reading env

2011-04-08T13:02:27+00:00

Flash might be in unknown state when u-boot is started with jtag.
And got wrong env data. So reset it in board early init.

We cannot use generic cfi flash routines, because flash_init() is
not run yet.

rename _end to __bss_end__

2011-03-27T17:18:37+00:00

Currently, _end is used for end of BSS section.  We want _end to mean
end of u-boot image, so we rename _end to __bss_end__ first.
