[U-Boot] [PATCH 1/6 V5] common: Add symbol handling for generic lists into Makefile
Marek Vasut
marex at denx.de
Fri Oct 19 17:00:10 CEST 2012
This patch adds essential components for generation of the contents of
the linker section that is used by the linker-generated array. All of
the contents is held in a separate file, u-boot.lst, which is generated
at runtime just before U-Boot is linked.
The purpose of this code is to especially generate the appropriate
boundary symbols around each subsection in the section carrying the
linker-generated arrays. Obviously, the interim linker code for actual
placement of the variables into the section is generated too. The
generated file, u-boot.lst, is included into u-boot.lds via the linker
INCLUDE directive in u-boot.lds .
Adjustments are made in the Makefile and spl/Makefile so that the
u-boot.lds and u-boot-spl.lds depend on their respective .lst files.

V2:
- Rebase on top of testing/dm-kerneldoc
- Fix INCLUDE u-boot.lds in linker scripts. It didn't work with older LD,
use #include instead and make use of CPP.
- Fix placement of u-boot.lds for NAND SPL
V3:
- Rebase on top of u-boot/next
- Put u-boot.lst into include/ , so the CPP finds it easily.
V4:
- Fix the MIPS breakage
V5:
- Fix top-level Makefile, which already has line-over-80 issue and it has
only gone worse with this patch adding more contents to such lines by
spliting these lines

+# make_u_boot_list - Generate contents of u_boot_list section
+# 1: The name of the resulting file (usually u-boot.lst)
+# 2: Files to analyze for possible u_boot_list entries
+#
+# This function generates the contents of the u_boot_list section,
+# including all the border symbols for it's subsections. The operation
+# of this function is as follows, numbering goes per lines:
+#
+# 1) Dump the ELF header sections from all files supplied via $(2)
+# 2) Filter out all other stuff that does not belong into .u_boot_list
+# section.
+# 3) Fix up the lines so that the resulting output is is in format
+# ".u_boot_list.*".
+# 4) Remove the last .something$, since that only contains the name
+# of the variable to be put into a subsection. This name is irelevant
+# for generation of border symbols, thus of no interest, remove it.
+# 5) Take each line and for every dot "." in that line, print the whole
+# line until that dot "." . This is important so that we have all
+# parent border symbols generated as well.
+# 6) Load every line and firstly append "\a" at the end and print the
+# line. Next, append "@" at the end and print the line. Finally,
+# append "~" at the end of line. This will make sense in conjunction
+# with 6) and 7).
+# 7) Sort the lines. It is imperative to use LC_COLLATE=C here because
+# with this, the "\a" symbol is first and "~" symbol is last. Any
+# other symbols fall inbetween. Symbols like "@", which marks the
+# end of current line (representing current section) and ".", which
+# means the line continues and thus represents subsection.
+# 8) With such ordering, all lines ending with "\a" will float at the
+# begining of all lines with the same prefix. Thus it is easy to
+# replace "\a" with __start and make it the __start border symbol.
+# Very similarly for "~", which will be always at the bottom and so
+# can be replaced by "__end" and made into the __end border symbol.
+# Finally, every line ending with "@" symbol will be transformed
+# into " *(SORT(${line}*)); " format, which in the linker parlance
+# will allow it to trap all symbols relevant to the subsection.
