2012-10-17split AU1X00 specific code from cmd_ide.cPavel Herrmann
move special case of ide_swap_read() for AU1X00 SoC into SoC-specific directory. Signed-off-by: Pavel Herrmann <morpheus.ibis@gmail.com>
2012-10-17split mpc8xx hooks from cmd_ide.cPavel Herrmann
move most of mpc8xx hooks from cmd_ide.c into ide_preinit() and newly created ide_init_postreset() (invoked after calling ide_reset after ide_preinit), some cleanup to make checkpatch happy, enable IDE init hooks in configs of affected boards. confusingly, these hooks are used by more than just mpc8xx-based boards, and therefore are placed in arch/ppc/lib/ note: checkpatch still emits warnings about using volatile Signed-off-by: Pavel Herrmann <morpheus.ibis@gmail.com>
2012-10-17serial: Use default_serial_puts() in driversMarek Vasut
Replace the in-place ad-hoc implementation of serial_puts() within the drivers with default_serial_puts() call. This cuts down on the code duplication quite a bit. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Marek Vasut <marek.vasut@gmail.com> Cc: Tom Rini <trini@ti.com>

2012-10-16mx6qsabreauto: Pass the board revision to the kernelFabio Estevam
The kernel from Freescale expects that the bootloader passes the board revision. Read the board revision and pass it via get_board_rev(). Without passing the board revision the kernel does not operate properly as the initialization of peripherals are different in revA versus revB boards.

2012-10-16mx35: Fix eSDHC clocksBenoît Thébaudeau
Each eSDHC instance has a dedicated clock. gd->sdhc_clk must also 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()).

2012-10-15mx31: Fix PDR0_CSI_PODFBenoît Thébaudeau
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: Benoît Thébaudeau <benoit.thebaudeau@advansee.com> Cc: Stefano Babic <sbabic@denx.de>

2012-10-15mx5: Optimize lowlevel_init code sizeBenoît Thébaudeau
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.

2012-10-15mx25: Fix eSDHC supportBenoît Thébaudeau
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()).

2012-10-15mx25: Define cpu_eth_init() only if neededBenoît Thébaudeau
The FEC is the only SoC Ethernet support available on i.MX25, so define cpu_eth_init() only for it instead of returning a misleading success code. Signed-off-by: Benoît Thébaudeau <benoit.thebaudeau@advansee.com> Cc: Stefano Babic <sbabic@denx.de>
2012-10-15mx25: Clean up clocks APIBenoît Thébaudeau
Use the standard mxc_get_clock() instead of exporting internal functions and using literal constant values. Signed-off-by: Benoît Thébaudeau <benoit.thebaudeau@advansee.com> Cc: Stefano Babic <sbabic@denx.de>
2012-10-15mx25 clocks: Fix MXC_FEC_CLKBenoît Thébaudeau
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: Benoît Thébaudeau <benoit.thebaudeau@advansee.com> Cc: Stefano Babic <sbabic@denx.de>

2012-10-15mx5/6 clocks: Fix SDHC clocksBenoît Thébaudeau
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()).

2012-10-15mx5 clocks: Fix MXC_FEC_CLKBenoît Thébaudeau
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).

2012-10-15mx5 clocks: Simplify imx_get_cspiclk()Benoît Thébaudeau
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. Signed-off-by: Benoît Thébaudeau <benoit.thebaudeau@advansee.com> Cc: Stefano Babic <sbabic@denx.de>
2012-10-15mx5 clocks: Fix get_uart_clk()Benoît Thébaudeau
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.

2012-10-15mx5 clocks: Fix get_ipg_per_clk()Benoît Thébaudeau
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: Benoît Thébaudeau <benoit.thebaudeau@advansee.com> Cc: Stefano Babic <sbabic@denx.de>
2012-10-15mx5 clocks: Fix get_periph_clk()Benoît Thébaudeau
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. Signed-off-by: Benoît Thébaudeau <benoit.thebaudeau@advansee.com> Cc: Stefano Babic <sbabic@denx.de>
2012-10-15mx5 clocks: Fix get_lp_apm()Benoît Thébaudeau
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.

2012-10-15mx5 clocks: Add and use CCSR definitionsBenoît Thébaudeau

2012-10-15mx51: Fix USB PHY clocksBenoît Thébaudeau
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 existing code was correct only for i.MX53, so this patch fixes the i.MX51 use case.

2012-10-15mx5: Fix clock gate valuesBenoît Thébaudeau
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.

2012-10-15mx5 clocks: CleanupBenoît Thébaudeau
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.
