2009-07-018xxx: Break out DMA code to a common filePeter Tyser
DMA support is now enabled via the CONFIG_FSL_DMA define instead of the previous CONFIG_DDR_ECC Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-06-12fsl/85xx, 86xx: Sync up DMA codePeter Tyser
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>
2009-06-12fsl: Create common fsl_dma.h for 85xx and 86xx cpusPeter Tyser
Break out DMA structures for the Freescale MPC85xx and MPC86xx cpus to reduce a large amount of code duplication Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-06-12qe: Pass in uec_info struct through uec_initializeHaiying Wang
The uec driver contains code to hard code configuration information for the uec ethernet controllers. This patch creates an array of uec_info structures, which are then parsed by the corresponding driver instance to determine configuration. It also creates function uec_standard_init() to initialize all UEC interfaces for 83xx and 85xx.

2009-03-30MPC85xx: Add MPC8569 CPU supportHaiying Wang
There is a workaround for MPC8569 CPU Errata, which needs to set Bit 13 of LBCR in 4K bootpage. We setup a temp TLB for eLBC controller in bootpage, then invalidate it after LBCR bit 13 is set.

2009-01-23Add secondary CPUs processor frequency for e500 coreHaiying Wang
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>
2008-12-19mpc8[56]xx: Put localbus clock in sysinfo and gdTrent Piepho
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.

2008-12-19mpc8568: Double local bus clock dividerTrent Piepho
The clock divider for the MPC8568 local bus should be doubled, like the other newer MPC85xx chips. Since there are now more chips with a 2x divider than a 1x, and any new 85xx chips will probably be 2x, invert the sense of the #if so that it lists the 1x chips instead of the 2x ones.

2008-12-19mpc8xxx: LCRR[CLKDIV] is sometimes five bitsTrent Piepho
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.

2008-09-02Pass in tsec_info struct through tsec_initializeAndy Fleming
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.

2008-06-1085xx: expose cpu identificationKumar Gala
The current cpu identification code is used just to return the name of the processor at boot. There are some other locations that the name is useful (device tree setup). Expose the functionality to other bits of code. Also, drop the 'E' suffix and add it on by looking at the SVR version when we print this out. This is mainly to allow the most flexible use of the name. The device tree code tends to not care about the 'E' suffix. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2008-03-26Update SVR numbers to expand supportAndy Fleming
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.
