2008-04-18Fix calculation of I2C clock for some 85xx chipsTimur Tabi
Some 85xx chips use CCB as the base clock for the I2C. Some use CCB/2, and some use CCB/3. There is no pattern that can be used to determine which chips use which frequency, so the only way to determine is to look up the actual SOC designation and use the right value for that SOC. Update immap_85xx.h to include the GUTS PORDEVSR2 register. Signed-off-by: Timur Tabi <timur@freescale.com>
2008-03-2685xx: Speed up get_ddr_freq() and get_bus_freq()James Yang
get_ddr_freq() and get_bus_freq() used get_sys_info() each time they were called. However, get_sys_info() recalculates extraneous information when called each time. Have get_ddr_freq() and get_bus_freq() return memoized values from global_data instead. Signed-off-by: James Yang <James.Yang@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2008-02-1485xx, 86xx: Determine I2C clock frequencies and store in global_dataTimur Tabi
Update global_data to define i2c1_clk and i2c2_clk to 85xx and 86xx. Update the get_clocks() function in 85xx and 86xx to determine the I2C clock frequency and store it in gd->i2c1_clk and gd->i2c2_clk. Signed-off-by: Timur Tabi <timur@freescale.com>
2007-12-11Handle Asynchronous DDR clock on 85xxKumar Gala
The MPC8572 introduces the concept of an asynchronous DDR clock with regards to the platform clock. Introduce get_ddr_freq() to report the DDR freq regardless of sync/async mode. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-12-11Stop using immap_t for cpm offset on 85xxKumar Gala
In the future the offsets to various blocks may not be in same location. Move to using CFG_MPC85xx_CPM_ADDR as the base of the CPM registers instead of getting it via &immap->im_cpm. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-12-11Stop using immap_t for guts offset on 85xxKumar Gala
In the future the offsets to various blocks may not be in same location. Move to using CFG_MPC85xx_GUTS_ADDR as the base of the guts registers instead of getting it via &immap->im_gur. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-04-23Reworked 85xx speed detection codeAndy Fleming
Changed the code to read the registers and calculate the clock rates, rather than using a "switch" statement. Idea from Andrew Klossner <andrew@cesa.opbu.xerox.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
2006-03-31GCC-4.x fixes: clean up global data pointer initialization for all boards.Wolfgang Denk
2005-07-23* Patch by Jon Loeliger, Kumar Gala 2005-02-08Jon Loeliger
- Convert the CPM2 based functionality to use new CONFIG_CPM2 option rather than a myriad of CONFIG_MPC8560-like variants. Applies to MPC85xx and MPC8260 boards, includes stxgp3 and sbc8560. Eliminates the CONFIG_MPC8560 option entirely. Distributes the new CONFIG_CPM2 option to each 8260 board.
2004-08-01* Code cleanupwdenk
* Patch by Sascha Hauer, 28 Jun: - add generic support for Motorola i.MX architecture - add support for mx1ads, mx1fs2 and scb9328 boards * Patches by Marc Leeman, 23 Jul 2004: - Add define for the PCI/Memory Buffer Configuration Register - corrected comments in cpu/mpc824x/cpu_init.c * Add support for multiple serial interfaces (for example to allow modem dial-in / dial-out)
