-A linker list is constructed by grouping together linker input
-sections, each containing one entry of the list. Each input section
-contains a constant initialized variable which holds the entry's
-content. Linker list input sections are constructed from the list
-and entry names, plus a prefix which allows grouping all lists
-together. Assuming _list and _entry are the list and entry names,
-then the corresponding input section name is
+.. toctree::
-::
-
- .u_boot_list_ + 2_ + @_list + _2_ + @_entry
-
-and the C variable name is
-
-::
-
- _u_boot_list + _2_ + @_list + _2_ + @_entry
-
-This ensures uniqueness for both input section and C variable name.
-
-Note that the names differ only in the first character, "." for the
-section and "_" for the variable, so that the linker cannot confuse
-section and symbol names. From now on, both names will be referred
-to as
-
-::
-
- %u_boot_list_ + 2_ + @_list + _2_ + @_entry
-
-Entry variables need never be referred to directly.
-
-The naming scheme for input sections allows grouping all linker lists
-into a single linker output section and grouping all entries for a
-single list.
-
-Note the two '_2_' constant components in the names: their presence
-allows putting a start and end symbols around a list, by mapping
-these symbols to sections names with components "1" (before) and
-"3" (after) instead of "2" (within).
-Start and end symbols for a list can generally be defined as
-
-::
-
- %u_boot_list_2_ + @_list + _1_...
- %u_boot_list_2_ + @_list + _3_...
-
-Start and end symbols for the whole of the linker lists area can be
-defined as
-
-::
-
- %u_boot_list_1_...
- %u_boot_list_3_...
-
-Here is an example of the sorted sections which result from a list
-"array" made up of three entries : "first", "second" and "third",
-iterated at least once.
-
-::
-
- .u_boot_list_2_array_1
- .u_boot_list_2_array_2_first
- .u_boot_list_2_array_2_second
- .u_boot_list_2_array_2_third
- .u_boot_list_2_array_3
-
-If lists must be divided into sublists (e.g. for iterating only on
-part of a list), one can simply give the list a name of the form
-'outer_2_inner', where 'outer' is the global list name and 'inner'
-is the sub-list name. Iterators for the whole list should use the
-global list name ("outer"); iterators for only a sub-list should use
-the full sub-list name ("outer_2_inner").
-
-Here is an example of the sections generated from a global list
-named "drivers", two sub-lists named "i2c" and "pci", and iterators
-defined for the whole list and each sub-list:
-
-::
-
- %u_boot_list_2_drivers_1
- %u_boot_list_2_drivers_2_i2c_1
- %u_boot_list_2_drivers_2_i2c_2_first
- %u_boot_list_2_drivers_2_i2c_2_first
- %u_boot_list_2_drivers_2_i2c_2_second
- %u_boot_list_2_drivers_2_i2c_2_third
- %u_boot_list_2_drivers_2_i2c_3
- %u_boot_list_2_drivers_2_pci_1
- %u_boot_list_2_drivers_2_pci_2_first
- %u_boot_list_2_drivers_2_pci_2_second
- %u_boot_list_2_drivers_2_pci_2_third
- %u_boot_list_2_drivers_2_pci_3
- %u_boot_list_2_drivers_3
