kerneldoc: Implant DocBook from Linux kernel
Pull slightly modified version of Documentation/DocBook, the related perl
script scripts/kernel-doc and the scripts/docproc.c from Linux kernel and
implant it into U-Boot. This will allow smooth generation of kerneldoc
style documentation.
It was necessary to modify the DocBook/Makefile to work with U-Boot build
system. The changes were only minor though and involved replacing the kbuild
specific parts.
It was also necessary to replace use of variables like KERNEL_VERSION with
U_BOOT_VERSION, strings like Linux kernel with U-Boot Bootloader etc. so
the generated result actually matches.
Finally, it was necessary to adjust docproc.c, since the documentation in
U-Boot is located in doc/DocBook instead of Documentation/DocBook as is in
case of the Linux kernel.
Some parts of the DocBook Makefile are unused, but to allow easier sync with
Linux kernel, these parts are still left in. The targets enabled now are
"htmldocs" "pdfdocs" "psdocs" "xmldocs" and "cleandocs" to remove the results
of documentation build.
Clean up mx25 lowlevel_init:
- Add comments.
- Do not use write32 repeatedly with the same value in order not to increase
code size.
- Make register values configurable.
- Use macro parameters with default values instead of literal constants.
- Use defined macros instead of duplicating code.
The CSI PODF bit-field used by the previous code for the i.MX31 CCM PDR0
register is actually composed of two bit-fields: one pre-divider and one
post-divider. This patch fixes the CCM access macros and the code using them
accordingly.
Optimize mx5 lowlevel_init.S code size:
- Compute values at compile time rather than at runtime where possible.
- Assign r4 to hold the zero value rather than setting registers to 0 again and
again.
- Associate a function to setup_pll rather than expanding its large macro code
multiple times.
- Allocate constant values in section only if used.
The MMC driver appropriate for the i.MX25 is fsl_esdhc, which has nothing to do
with mxcmmc.
Also, each eSDHC instance has a dedicated clock, so gd->sdhc_clk must be set
accordingly. This is good for the case only a single SDHC instance is used
(initialization made with fsl_esdhc_mmc_init()). A future patch will fix the
multi-instance use case (initialization made directly with
fsl_esdhc_initialize()).

The i.MX5 eSDHC clocks were considered as coming from the IPG clock although
they have dedicated clock paths.
Also, on i.MX5/6, each SDHC instance has a dedicated clock, so gd->sdhc_clk must
be set accordingly. This is good for the case only a single SDHC instance is
used (initialization made with fsl_esdhc_mmc_init()). A future patch will fix

The FEC clock does not come from PLL1, but from the IPG clock. The previous code
was even inconsistent with itself, returning the IPG clock as expected for
imx_get_fecclk(), but the PLL1 clock for mxc_get_clock(MXC_FEC_CLK).
The code handling the dividers was duplicated for each possible input clock, and
this function can benefit from the newly introduced get_standard_pll_sel_clk()
function instead of duplicating this mux handling code.
This function returned 66500000 instead of the correct lp_apm clock frequency if
the CCM.CSCMR1.uart_clk_sel mux is set to 3.
This patch fixes this issue by introducing the get_standard_pll_sel_clk()
function that will be used by future patches to handle identical muxes used by
many other clocks.
This fixes the "IPG PERCLK" frequency printed by the clocks command. The issue
was that get_ipg_per_clk() used periph_clk instead of lp_apm in the case
CCM.CBCMR.perclk_lp_apm_sel is set.
In the case periph_clk comes from periph_apm_clk, the latter is selected by the
CCM.CBCMR.periph_apm_sel mux, which can source the lp_apm clock from its
input ♯2. get_periph_clk() returned 0 instead of the lp_apm clock frequency in
this case.
If CCM.CCSR.lp_apm is set, the lp_apm clock is not necessarily 32768 Hz x 1024.
In that case:
- on i.MX51, this clock comes from the output of the FPM,
- on i.MX53, this clock comes from the output of PLL4.
The clock gate values are 2-bit bit-fields. Hence, setting or clearing only one
of these bits like what was done is wrong and can lead to unpredictable behavior
depending on the original value of these bit-fields.
Clean up the i.MX5 clock driver:
- Use readl() and writel() instead of their __raw_ counterparts.
- Use the clr/setbits_le32() family of macros rather than expanding code.
- Use accessor macros for bit-fields instead of _MASK and _OFFSET.
