Fix incorrect use of getenv() before relocation

2011-05-12T17:48:42+00:00

A large number of boards incorrectly used getenv() in their board init
code running before relocation.  In some cases this caused U-Boot to
hang when certain environment variables grew too long.
Fix the code to use getenv_r().

mpc85xx boards: initdram() cleanup/bugfix

2011-01-14T07:32:19+00:00

Correct initdram to use phys_size_t to represent the size of
dram; instead of changing this all over the place, and correcting
all the other random errors I've noticed, create a
common initdram that is used by all non-corenet 85xx parts.  Most
of the initdram() functions were identical, with 2 common differences:

1) DDR tlbs for the fixed_sdram case were set up in initdram() on
some boards, and were part of the tlb_table on others.  I have
changed them all over to the initdram() method - we shouldn't
be accessing dram before this point so they don't need to be
done sooner, and this seems cleaner.

2) Parts that require the DDR11 erratum workaround had different
implementations - I have adopted the version from the Freescale
errata document.  It also looks like some of the versions were
buggy, and, depending on timing, could have resulted in the
DDR controller being disabled.  This seems bad.

The xpedite boards had a common/fsl_8xxx_ddr.c; with this
change only the 517 board uses this so I have moved the ddr code
into that board's directory in xpedite517x.c

powerpc/8xxx: Replace is_fsl_pci_cfg with is_serdes_configured

2011-01-14T07:32:19+00:00

Now that we have serdes support for all 85xx/86xx/Pxxx chips we can
replace the is_fsl_pci_cfg() code with the is_serdes_configured().

Switch from archive libraries to partial linking

2010-11-17T20:02:18+00:00

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.

fsl: Clean up printing of PCI boot info

2010-11-14T22:46:42+00:00

Previously boards used a variety of indentations, newline styles, and
colon styles for the PCI information that is printed on bootup.  This
patch unifies the style to look like:

...

PCIE1: connected as Root Complex
           Scanning PCI bus 01
        04  01  8086  1010  0200  00

xes: Add board_flash_wp_on()

2010-10-22T07:17:19+00:00

Add board_flash_wp_on() to check a pca9557 gpio pin to see
if non-volatile memory write protection is enabled.

Previously, write protected NOR flashes would fail initialization which
resulted in a bootup error such as:

 ...
 DTT:   53 C local / 64 C remote (adt7461@4c)
 DTT:   54 C local (ds1621@48)
 FLASH: Executed from FLASH1
 POST memory PASSED
 FLASH: ## Unknown FLASH on Bank 1 - Size = 0x00000000 = 0 MB
 ## Unknown FLASH on Bank 2 - Size = 0x00000000 = 0 MB
 *** failed ***
 ### ERROR ### Please RESET the board ###

With this patch, NOR flash initialization is skipped:

 ...
 DTT:   53 C local / 64 C remote (adt7461@4c)
 DTT:   54 C local (ds1621@48)
 FLASH: Executed from FLASH1
 POST memory PASSED
 FLASH: Uninitialized - Write Protect On
 L2:    1024 KB enabled
 NAND:  1024 MiB
 ...

Note that flash related commands such as flinfo and saveenv will error
out when flash write protection is enabled.

xes: Consolidate checkboard()

2010-10-22T07:17:16+00:00

Create a common checkboard() function to support all X-ES's Freescale
boards.

Also, add a get_board_derivative() function which reads hardware
strapping resistors to determine what model a board is.  This allows one
U-Boot image to support multiple boards.
