* fsl/85xx, 86xx: Sync up DMA codePeter Tyser2009-06-12-6/+8
| | | | | | | | | | | | | | | | | | | | | The following changes were made to sync up the DMA code between the 85xx and 86xx architectures which will make it easier to break out common 8xxx DMA code: 85xx: - Don't set STRANSINT and SPCIORDER fields in SATR register. These bits only have an affect when the SBPATMU bit is set. - Write 0xffffffff instead of 0xfffffff to clear errors in the DMA status register. We may as well clear all 32 bits of the register... 86xx: - Add CONFIG_SYS_MPC86xx_DMA_ADDR define to address DMA registers - Add clearing of errors in the DMA status register when initializing the controller - Clear the channel start bit in the DMA mode register after a transfer Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* Replace __attribute references with __attribute__Peter Tyser2009-04-28-1/+1
| | | | | | | | __attribute__ follows gcc's documented syntax and is generally more common than __attribute. This change is only asthetic and should not affect functionality. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>

* 86xx: Reset updatePeter Tyser2009-02-16-61/+19
| | | | | | | | | | Update the 86xx reset sequence to try executing a board-specific reset function. If the board-specific reset is not implemented or does not succeed, then assert #HRESET_REQ. Using #HRESET_REQ is a more standard reset procedure than the previous method and allows all board peripherals to be reset if needed. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>

* mpc8[56]xx: Put localbus clock in sysinfo and gdTrent Piepho2008-12-19-18/+4
| | | | | | | | | | | | | | | | | | | | | | | 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.

* mpc8xxx: LCRR[CLKDIV] is sometimes five bitsTrent Piepho2008-12-19-1/+1
| | | | | | | | | | | | | | 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.

* Pass in tsec_info struct through tsec_initializeAndy Fleming2008-09-02-19/+7
| | | | | | | | | | | | | The tsec driver contains a hard-coded array of configuration information for the tsec ethernet controllers. We create a default function that works for most tsecs, and allow that to be overridden by board code. It creates an array of tsec_info structures, which are then parsed by the corresponding driver instance to determine configuration. Also, add regs, miiregs, and devname fields to the tsec_info structure, so that we don't need the kludgy "index" parameter.

* Update SVR numbers to expand supportAndy Fleming2008-03-26-1/+1
| | | | | | | | | | | | | FSL has taken to using SVR[16:23] as an SOC sub-version field. This is used to distinguish certain variants within an SOC family. To account for this, we add the SVR_SOC_VER() macro, and update the SVR_* constants to reflect the larger value. We also add SVR numbers for all of the current variants. Finally, to make things neater, rather than use an enormous switch statement to print out the CPU type, we create and array of SVR/name pairs (using a macro), and print out the CPU name that matches the SVR SOC version.

* 86xx: Convert sbc8641d to use libfdt.Jon Loeliger2008-02-18-61/+0
| | | | | | | | | | | | | | | This is the proper fix for a missing closing brace in the function ft_cpu_setup() noticed by joe.hamman <at> embeddedspecialties.com. The ft_cpu_setup() function in mpc8641hpcn.c should have been removed earlier as it was under the obsolete CONFIG_OF_FLAT_TREE, but was missed. Only, the sbc8641d was nominally still using it. It all got ripped out, and the funcality that was in ft_board_setup() was refactored to remove the CPU portions into the new file cpu/mpc86xx/fdt.c instead. Make sbc8641d use this now. Based loosely on an original patch from joe.hamman@embeddedspecialties.com Signed-off-by: Jon Loeliger <jdl@freescale.com>
