| | | | | | | | | | | | | | | | | | | | | | | | Since this define is only used on one board that was never really in production, removing this compile time option doesn't hurt and makes the code more readable. Signed-off-by: Stefan Roese <sr@denx.de>
| * | ppc4xx: Fix compilation warning for PIP405Stefan Roese2008-09-08-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a compilation warning for the PIP405 board. It moves the #ifndef CONFIG_CS8952_PHY define a little so that the warning doesn't occur anymore. I am a little unsure if this #ifdef is at the correct place now or if it could be removed completely. This needs to get tested on the PIP405 board. Signed-off-by: Stefan Roese <sr@denx.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Alternate SDRAM DDR autocalibration routine that can be generically used for any PPC4xx chips that have the IBM SDRAM Controller core allowing for support of more DIMM/memory chip vendors and gets the DDR autocalibration values which give the best read latency performance (SDRAM0_RDCC.[RDSS]). Two alternate SDRAM DDR autocalibration algoritm are provided in this patch, "Method_A" and "Method_B". DDR autocalibration Method_A scans the full range of possible PPC4xx SDRAM Controller DDR autocalibration values and takes a lot longer to run than Method_B. Method_B executes in the same amount of time as the currently existing DDR autocalibration routine, i.e. 1 second or so. Normally Method_B is used and it is set as the default method. The current U-Boot PPC4xx DDR autocalibration code calibrates the IBM SDRAM Controller registers.[bit-field]: 1) SDRAM0_RQDC.[RQFD] 2) SDRAM0_RFDC.[RFFD] This alternate PPC4xx DDR autocalibration code calibrates the following IBM SDRAM Controller registers.[bit-field]: 1) SDRAM0_WRDTR.[WDTR] 2) SDRAM0_CLKTR.[CKTR] 3) SDRAM0_RQDC.[RQFD] 4) SDRAM0_RFDC.[RFFD] and will also use the calibrated settings of the above four registers that produce the best "Read Sample Cycle Select" value in the SDRAM0_RDCC.[RDSS] register.[bit-field].

* | | ARM: fix warning: target CPU does not support interworkingSergei Poselenov2008-09-09-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes warnings like this: start.S:0: warning: target CPU does not support interworking which come from some ARM cross compilers and are caused by hard-coded (with "--with-cpu=arm9" configuration option) ARM targets (which support ARM Thumb instructions), while the ARM target selected from the command line (with "-march=armv4") doesn't support Thumb instructions. This warning is issued by the compiler regardless of the real use of the Thumb instructions in code. To fix this problem, we use options according to compiler version being used.

| * mpc83xx: Store and display Arbiter Event Register valuesNick Spence2008-09-03-1/+146
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Record the Arbiter Event Register values and optionally display them. The Arbiter Event Register can record the type and effective address of an arbiter error, even through an HRESET. This patch stores the values in the global data structure. Display of the Arbiter Event registers immediately after the RSR value can be enabled with defines. The Arbiter values will only be displayed if an arbiter event has occured since the last Power On Reset, and either of the following defines exist: #define CONFIG_DISPLAY_AER_BRIEF - display only the arbiter address and and type register values #define CONFIG_DISPLAY_AER_FULL - display and interpret the arbiter event register values Address Only transactions are one of the trapped events that can register as an arbiter event. They occur with some cache manipulation instructions if the HID0_ABE (Address Broadcast Enable) is set and the memory region has the MEMORY_COHERENCE WIMG bit set. Setting: #define CONFIG_MASK_AER_AO - prevents the arbiter from recording address only events, so that it can still capture other real problems.

| * mpc83xx: use r4 instead of r2 in lock_ram_in_cache and unlock_ram_in_cacheNick Spence2008-09-03-4/+5
| | | | | | | | | | | | | | | | | | | | | | This is needed in unlock_ram_in_cache() because it is called from C and will corrupt the small data area anchor that is kept in R2. lock_ram_in_cache() is modified similarly as good coding practice, but is not called from C.

| * MPC83XX: Fix GPIO configuration - set gpio level before directionNick Spence2008-09-03-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Set DAT value before DIR values to avoid creating glitches on the GPIO signals. Set gpio level register before direction register to inhibit glitches on high level output pins. Dir and data gets cleared at powerup, so high level output lines see a short low pulse between setting the direction and level registers. Issue was seen on a new board with the nReset line of the NOR flash connected to a GPIO. Setting the direction register puts the NOR flash in reset so the next instruction to set the level cannot get executed.

|/ | | | | | | | | | | | | 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.
