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. Linux scripts/docproc.c: commit f0f3ca8d967462dafb815412b14ca3339b9817a6 Date: Wed Jun 15 11:53:13 2011 +0200 Linux scripts/kernel-doc: commit 1b40c1944db445c1de1c47ffd8cd426167f488e8 Date: Sun Aug 12 10:46:15 2012 +0200 Linux Documentation/DocBook: commit bb8187d35f820671d6dd76700d77a6b55f95e2c5 Date: Thu May 17 19:06:13 2012 -0400 Signed-off-by: NMarek Vasut <marex@denx.de>

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. Signed-off-by: NBenoît Thébaudeau <benoit.thebaudeau@advansee.com> Cc: Stefano Babic <sbabic@denx.de>

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()).

mxc_get_clock(MXC_FEC_CLK) should return the IPG clock, not the AHB clock. Also, imx_get_fecclk() was correct but reimplemented the calculation of the IPG clock, so remove the duplicated code. Signed-off-by: NBenoît Thébaudeau <benoit.thebaudeau@advansee.com> Cc: Stefano Babic <sbabic@denx.de>

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 multi-instance use case (initialization made directly with fsl_esdhc_initialize()).

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. It also fixes I²C support. Signed-off-by: NBenoît Thébaudeau <benoit.thebaudeau@advansee.com> Cc: Stefano Babic <sbabic@denx.de>

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. This patch fixes the code accordingly.

The i.MX51 has a single USB PHY clock, while the i.MX53 has two. These 3 clocks have different clock gate control bit-fields.

The clock gate values are 2-bit bit-fields.
