2011-07-26serial: drop useless ctlr fieldMike Frysinger
The multi serial support has a "ctlr" field which almost no one uses, but everyone is forced to set to useless strings. So punt it. Funny enough, the only code that actually reads this field (the mpc8xx driver) has a typo where it meant to look for the SCC driver. Fix it while converting the check to use the name field.

2011-07-26serial: push default_serial_console to driversMike Frysinger
Rather than sticking arch/board/driver specific logic in the common serial code, push it all out to the respective drivers. The serial drivers declare these funcs weak so that boards can still override things with their own definition.

2011-07-22powerpc/mpc85xx: Add clear_ddr_tlbs functionBecky Bruce
This is useful when we just want to wipe out the TLBs. There's currently a function that resets the ddr tlbs to a different value; it is changed to utilize this function. The new function can be used in conjunction with setup_ddr_tlbs() for a board to temporarily map/unmap the DDR address range as needed.

2011-07-22fman: insert the Fman firmware into the device treeTimur Tabi
The Fman device tree node binding allows for the entire Fman firmware binary data to be embedded in the device tree. This eliminates the need to have NOR flash mapped to Linux just so that the Fman driver can see the firmware. The location of the Fman firmware is taken from the 'fman_ucode' environment variable.

2011-07-22powerpc/85xx: add support the ePAPR "phandle" propertyTimur Tabi
The ePAPR specification says that phandle properties should be called "phandle", and not "linux,phandle". To facilitate the migration from "linux,phandle" to "phandle", we update fdt_qportal() to use the new function, fdt_create_phandle(). This function abstracts the creation of phandle properties.

2011-07-11powerpc/85xx: remove SERDES4 soft-reset work-aroundTimur Tabi
Some P4080 rev1 errata work-arounds, notably erratum SERDES4, required a bank soft-reset after the bank was configured and enabled, even though enabling a bank causes it to reset. Because the reset was required for multiple errata, it was not properly enclosed in an #ifdef, and so was not removed with all the other rev1 errata work-arounds. Erratum SERDES-8 says that the clocks for bank 3 needs to be enabled if bank 2 is enabled, but this was not being done for SERDES protocols 0xF and 0x10. The bank reset also happened to enable bank 3 (apparently an undocumented feature). Simply removing the reset breaks these two protocols. It turns out that every time we call enable_bank(), we do want at least one lane of the bank enabled, either because the bank is supposed to be enabled, or because we need the clock from that bank enabled. For erratum SERDES-A001, we don't want to modify srds_lpd_b[] when we call enable_bank(), because that array is used elsewhere to determine if the bank is available. Note that the side effect of these changes is that the work-arounds for these two errata are now linked. Specifically, if SERDES-A001 is enabled, then we need SERDES-8 enabled as well. Because this was the only SERDES bank soft-reset, there is no need to implement a work-around for erratum SERDES-A003. Also fix an off-by-one error in a printf().

APM errata CHIP_21 for the 405EX/EXr (from the rev 1.09 document dated 4/27/11) states that rev D processors may wake up with the wrong feature set. This patch implements the APM-proposed workaround. To enable this patch for your board, add the appropriate define for your CPU to your board header file. See kilauea.h for more information. The following variants are supported: #define CONFIG_SYS_4xx_CHIP_21_405EX_NO_SECURITY #define CONFIG_SYS_4xx_CHIP_21_405EX_SECURITY #define CONFIG_SYS_4xx_CHIP_21_405EXr_NO_SECURITY #define CONFIG_SYS_4xx_CHIP_21_405EXr_SECURITY Please note that if you select the wrong define, your board will not boot, and JTAG will be required to recover.

2011-04-28powerpc: use 'video-mode' environment variable to configure DIUTimur Tabi
Use the 'video-mode' environment variable (for Freescale chips that have a DIU display controller) to designate the full video configuration. Previously, the DIU driver used the 'monitor' variable, and it was used only to determine the output video port. The old definition of the "monitor" environment variable only determines which video port to use for output. This variable was set to a number (0, 1, or sometimes 2) to specify a DVI, LVDS, or Dual-LVDS port. The resolution was hard-coded into board-specific code. The Linux command-line arguments needed to be hard-coded to the proper video definition string. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Anatolij Gustschin <agust@denx.de>

2011-04-20fsl: Change fsl_phy_enet_if to phy_interface_tAndy Fleming
The fsl_phy_enet_if enum was, essentially, the phy_interface_t enum. This meant that drivers which used fsl_phy_enet_if to deal with PHY interfaces would have to convert between the two (or we would have to have them mirror each other, and deal with the ensuing maintenance headache). Instead, we switch all clients of fsl_phy_enet_if over to phy_interface_t, which should become the standard, anyway.
