* Add secondary CPUs processor frequency for e500 coreHaiying Wang2009-01-23-4/+6
| | | | | | | | | This patch updates e500 freqProcessor to array based on CONFIG_NUM_CPUS, and prints each CPU's frequency separately. It also fixes up each CPU's frequency in "clock-frequency" of fdt blob. Signed-off-by: James Yang <James.Yang@freescale.com> Signed-off-by: Haiying Wang <Haiying.Wang@freescale.com>
* mpc8[56]xx: Put localbus clock in sysinfo and gdTrent Piepho2008-12-19-0/+27
| | | | | | | | | | | | | | | | | | | | | | | Currently MPC85xx and MPC86xx boards just calculate the localbus frequency and print it out, but don't save it. This changes where its calculated and stored to be more consistent with the CPU, CCB, TB, and DDR frequencies and the MPC83xx localbus clock. The localbus frequency is added to sysinfo and calculated when sysinfo is set up, in cpu/mpc8[56]xx/speed.c, the same as the other frequencies are. get_clocks() copies the frequency into the global data, as the other frequencies are, into a new field that is only enabled for MPC85xx and MPC86xx. checkcpu() in cpu/mpc8[56]xx/cpu.c will print out the local bus frequency from sysinfo, like the other frequencies, instead of calculating it on the spot.

* | Revert "85xx: Using proper I2C source clock divider for MPC8544"Kumar Gala2008-10-17-2/+2
|/ | | | | | | | | | This reverts commit dffd2446fb041f38ef034b0fcf41e51e5e489159. The fix introduced by this patch is not correct. The problem is that the documentation is not correct for the MPC8544 with regards to which bit in PORDEVSR2 is for the SEC_CFG. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* 85xx: Using proper I2C source clock divider for MPC8544Wolfgang Grandegger2008-10-08-2/+2
| | | | | | | | | Measurements with our MPC8544 board showed that the I2C bus frequency is wrong by a factor of 1.5. Obviously, the interpretation of the MPC85xx_PORDEVSR2_SEC_CFG bit of the cfg_sec_freq register is not correct. There seems to be an error in the 8544 RM.

* Fix the incorrect DDR clk freq reporting on 8536DSJason Jin2008-10-07-1/+2
| | | | | | | | | On 8536DS board, When the DDR clk is set async mode(SW3[6:8] != 111), The display is still sync mode DDR freq. This patch try to fix this. The display DDR freq is now the actual freq in both sync and async mode. Signed-off-by: Jason Jin <Jason.jin@freescale.com>
* mpc85xx: Add support for the MPC8536Kumar Gala2008-08-27-0/+4
| | | | | | | | | | | The MPC8536 Adds SDHC and SATA controllers to the PQ3 family. We also have SERDES init code for the 8536.

* Fix calculation of I2C clock for some 85xx chipsTimur Tabi2008-04-18-1/+30
| | | | | | | | | | | 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>
* 85xx: Speed up get_ddr_freq() and get_bus_freq()James Yang2008-03-26-16/+5
| | | | | | | | | | 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>
* 85xx, 86xx: Determine I2C clock frequencies and store in global_dataTimur Tabi2008-02-14-0/+3
| | | | | | | | | 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>
* Handle Asynchronous DDR clock on 85xxKumar Gala2007-12-11-0/+25
| | | | | | | | | | 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>
* Stop using immap_t for cpm offset on 85xxKumar Gala2007-12-11-3/+3
| | | | | | | | 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>
* Stop using immap_t for guts offset on 85xxKumar Gala2007-12-11-2/+1
| | | | | | | | 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>
* Reworked 85xx speed detection codeAndy Fleming2007-04-23-36/+8

* * Patch by Jon Loeliger, Kumar Gala 2005-02-08Jon Loeliger2005-07-23-2/+2
| | | | | | | | - 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.
