spl: dm: Kconfig: split REGMAP/SYSCON support for TPL from SPL

2017-08-13T15:12:20+00:00

This change introduces TPL variants of the REGMAP and SYSCON config
options (i.e. TPL_REGMAP and TPL_SYSCON in analogy to SPL_REGMAP and
SPL_SYSCON) in preparation of a finer-grained feature selection for
building feature-rich TPL variants.

spl: dm: Kconfig: use more specific prereqs for SPL_REGMAP and SPL_SYSCON

2017-08-13T15:12:20+00:00

SPL_REGMAP and SPL_SYSCON were marked as depending on DM, when a
stricter dependency of SPL_DM was possible.  This commit makes the
prereq more specific.

dm: core: add ofnode_count_phandle_with_args()

2017-07-28T21:34:08+00:00

This function is usefull to get phandle number contained
in a property list.
For example,  this allows to allocate the right amount
of memory to keep clock's reference contained into the
"clocks" property.

To implement it, either of_count_phandle_with_args() or
fdtdec_parse_phandle_with_args() are used respectively
for live tree and flat tree.
By passing index = -1, these 2 functions returns the
number of phandle contained into the property list.

Add also the dev_count_phandle_with_args() based on
ofnode_count_phandle_with_args()

dm: core: Fix up ofnode_get_addr_index() for 64-bit values

2017-07-28T18:02:47+00:00

At present this function only supports 32-bit (single-cell) values. Update
it to support two-cell values also.

dm: core: Add ofnode_read_resource()

2017-07-28T18:02:47+00:00

We sometimes need to read a resource from an arbitrary node. In any case
for consistency we should not put the live-tree switching code in
a dev_read_...() function. Update this to suit.

dm: ofnode: change return type of dev_read_prop() to opaque pointer

2017-07-28T18:02:47+00:00

DT property values can be strings as well as integers.  This is why
of_get_property/fdt_getprop returns an opaque pointer.

spl: make SPL and normal u-boot stage use independent SYS_MALLOC_F_LEN

2017-07-27T12:59:03+00:00

Some platforms have very limited SRAM to run SPL code, so there may
not be the same amount space for a malloc pool before relocation in
the SPL stage as the normal U-Boot stage.

Make SPL and (the full) U-Boot stage use independent SYS_MALLOC_F_LEN,
so the size of pre-relocation malloc pool can be configured memory
space independently.

dm: ofnode: use fdt32_t for DT property value to fix sparse warning

2017-07-11T16:08:20+00:00

DTB is encoded in big endian.  When we retrieve property values,
we need to use fdt32_to_cpu (aka be32_to_cpu) for endian conversion.
This is a bit error-prone, but sparse is useful to detect endian
mismatch.

We need to use (fdt32_t *) instead of (u32 *) for a pointer of a
property value.  Otherwise sparse warns "cast to restricted __be32".

Include  to fix sparse warnings:
symbol 'dm_dump_all' was not declared. Should it be static?
symbol 'dm_dump_uclass' was not declared. Should it be static?
