On newer CPUs, 8536, 8572, and 8610, the CLKDIV field of LCRR is five bits instead of four. In order to avoid an ifdef, LCRR_CLKDIV is set to 0x1f on all systems. It should be safe as the fifth bit was defined as reserved and set to 0. Code that was using a hard coded 0x0f is changed to use LCRR_CLKDIV.

since commit be0bd8234b9777ecd63c4c686f72af070d886517 tlb entry for socrates DDR SDRAM will be reconfigured by setup_ddr_tlbs() from initdram() causing an inconsistency with previously configured DDR SDRAM tlb entry from tlb_table: socrates>l2cam 7 9 IDX PID EPN SIZE V TS RPN U0-U3 WIMGE UUUSSS 7 : 00 00000000 256MB V 0 -> 0_00000000 0000 -I-G- ---RWX 8 : 00 00000000 256MB V 0 -> 0_00000000 0000 ----- ---RWX 9 : 00 10000000 256MB V 0 -> 0_10000000 0000 ----- ---RWX This patch makes the presence of the DDR SDRAM tlb entry in the tlb_table dependent on CONFIG_SPD_EEPROM to avoid this inconsistency.

Most of the bss initialization loop increments 4 bytes at a time. And the loop end is checked for an 'equal' condition. Make the bss end address aligned by 4, so that the loop will end as expected.

Because some dimm parameters like n_ranks needs to be used with the board frequency to choose the board parameters like clk_adjust etc. in the board_specific_paramesters table of the board ddr file, we need to pass the dimm parameters to the board file. * move ddr dimm parameters header file from /cpu to /include directory. * add ddr dimm parameters to populate board specific options. * Fix fsl_ddr_board_options() for all the 8xxx boards which call this function.

Currently U-Boot crashes after relocation to RAM. Changing the CPO value of the DDR SDRAM TIMING_CFG_2 register to READ_LAT + 1 (to the value it was before conversion of socrates to new DDR code) fixes the problem. Signed-off-by: Anatolij Gustschin <agust@denx.de>
This patch is an attempt to implement autoprobing for the Lime presence on the bus. Configure GPCM for Lime CS2 and try to access chip ID registers. Second read atempt delivers register values if the chip is present. Signed-off-by: Anatolij Gustschin <agust@denx.de>

This patch adds Lime GDC support together with support for the PWM backlight control through the w83782d chip. The reset pin of the latter is attached to GPIO, so we need to reset it in early_board_init_r. Signed-off-by: Anatolij Gustschin <agust@denx.de>
- Update the local bus ranges in the FDT for Linux for the various devices connected to the local bus via chip-select. - Set the LCRR_DBYP bit in the LCRR for local bus frequencies lower than 66 MHz and uses I/O accessor functions consequently. - UPM data update. - Update of default environment and configuration. Use I2C multibus as we do have two I2C buses. Also enable sdram and ext2 commands.
