578ac1e9ba bootstage: Make use of BOOTSTAGE_ID_RUN_OS in show_boot_progress()
This changes the number 15 as used in boot_stage_progress() to use the
new name provided for it. This is a separate patch because it touches
so many files.

464c79207c punt unused clean/distclean targets
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.

6d8962e814 Switch from archive libraries to partial linking
Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

8f54dd4f13 a4m072: change 'display' command implementation
This patch changes implementation of 'display' command for a4m072
that uses 7-segment LED display as customer requested:

a) The "display" command shall _not_ turn on the decimal point.

b) Exception: "display ." shall turn on (only) the decimal point.

c) Hex digits (0-9, A-F, a-f) shall be displayed as usual.

d) Letters U, P, Y, L, S, T, H shall be displayed as usual (lower
   case letters identical to upper case letters)

e) 'I' (and 'i') shall be displayed like '1'

f) 'O' (and 'o') shall be displayed like '0'

g) all other Characters shall be displayed like ' ' (all segments off).

c8d76eaf60 Rename TEXT_BASE: fix merge conflicts
Commit 14d0a02a "Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE" missed a
few places, especially for boards that were added inbetween. Fix the
remaining issues.

92d1a400bc a4m072: support for SHOW_BOOT_PROGRESS feature using LED display
This patch adds support for displaying boot progress codes on a4m072 board
using LED display. As we can display only one symbol at any time on the hardware
(two symbols with blinking) we can't display progress codes directly and have
to map them to 2-symbol codes.
We use the following mapping on the a4m972 board:
 [1, 8] U [100, 108]					-> 5
 [-9, -1] U [-101, -100] U [-113, -103]			-> -5
 [9, 14] U [120, 123] U [125, 129]			-> 8
 [-13, -10] U [-122, -120] U [-127, -124] U {-129}	-> -8
 {15}							-> 9
 [-32, -30]						-> -A
 [-40, -35] U [-51, -42] U [-58, -53] U
		[-83, -80] U {-64, -130, -140, -150}	-> -B

Other progress code are ignored. One symbol codes are displayed steady while
two-symbol codes are displayed using blinking. Boot progress codes are
displayed with decimal got unset (as opposed to 'display' command output).

cb5639cbc0 a4m072: led display support
This patch adds support for LED display on a4m072 board. Hardware is
capable of displaying only one symbol at any time. We support displaying
two symbols in software (via blinking).
