* ppc4xx: Fix 440EPx bug in reconfigure_pll()Stefan Roese2010-09-03-0/+1
| | | | | | | | | | | | | | | | This patch fixes a bug in reconfigure_pll(), where the detection of the current bootstrap option is wrong. The ICS bits where incorrectly shifted. This bug was found on the lwmon5 board, which uses bootstrap option H (I2C bootstrap EEPROM). Additionally a bit of code was moved into the if statement, since its only used after later on. No need to run this code all the time. Also, a few empty lines are added to make the code better readable.

* ppc4xx: Enable booting with Option E on 460EX/EXr/GTStefan Roese2010-07-01-0/+7
| | | | | | | | | This patch enables booting with option E on the PPC460EX/EXr/GT. When booting with Option E, the PLL is in bypass, CPR0_PLLC[ENG]=0. The Software Boot Configuration Procedure is needed to engage the PLL and perform a chip reset. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx fix unstable 440EPx bootstrap optionsRupjyoti Sarmah2010-03-24-0/+6
| | | | | | | | | | | | | | 440EPx fixed bootstrap options A, B, D, and E sets PLL FWDVA to a value = 1. This results in the PLLOUTB being greater than the CPU clock frequency resulting unstable 440EPx operation resulting in various software hang conditions. This patch reprograms the FWDVA satisfying the requirement of setting FWDVB to a value greater than 1 while using one of the four deafult bootstrap options.

* ppc4xx: Cleanup PPC4xx I2C infrastructureStefan Roese2009-11-23-19/+0
| | | | | | | | | | | This patch cleans up the PPC4xx I2C intrastructure: - Use C struct to describe the I2C registers instead of defines - Coding style cleanup (braces, whitespace, comments, line length) - Extract common code from i2c_read() and i2c_write() - Remove unneeded IIC defines from ppc405.h & ppc440.h Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Consolidate pci_pre_init() functionStefan Roese2009-11-19-1/+2
| | | | | | | | | This patch removes the duplicted implementations of the pci_pre_init() function by introducing a weak default function for it. This weak default has a different implementation for some PPC variants. It can be overridden by a board specific version. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Add function to check and dynamically change PCI sync clockStefan Roese2009-10-23-1/+6
| | | | | | | | | | | | | | | | | | PPC440EP(x)/PPC440GR(x): In asynchronous PCI mode, the synchronous PCI clock must meet certain requirements. The following equation describes the relationship that must be maintained between the asynchronous PCI clock and synchronous PCI clock. Select an appropriate PCI:PLB ratio to maintain the relationship: AsyncPCIClk - 1MHz <= SyncPCIclock <= (2 * AsyncPCIClk) - 1MHz This patch now adds a function to check and reconfigure the sync PCI clock to meet this requirement. This is in preparation for some AMCC boards (Sequoia/Rainier and Yosemite/Yellowstone) using this function to not violate the PCI clocking rules. Signed-off-by: Stefan Roese <sr@denx.de>

* ppc4xx: Big cleanup of PPC4xx definesStefan Roese2009-09-11-296/+136
| | | | | | | | | | | | | | | | This patch cleans up multiple issues of the 4xx register (mostly DCR, SDR, CPR, etc) definitions: - Change lower case defines to upper case (plb4_acr -> PLB4_ACR) - Change the defines to better match the names from the user's manuals (e.g. cprpllc -> CPR0_PLLC) - Removal of some unused defines Please test this patch intensive on your PPC4xx platform. Even though I tried not to break anything and tested successfully on multiple 4xx AMCC platforms, testing on custom platforms is recommended. Signed-off-by: Stefan Roese <sr@denx.de>
* Dual-license IBM code contributionsJosh Boyer2009-08-09-0/+2
| | | | | | | | | | | | | It was brought to our attention that U-Boot contains code derived from the IBM OpenBIOS source code originally provided with some of the older PowerPC 4xx development boards. As a result, the original license of this code has been carried in the various files for a number of years in the U-Boot project. IBM is dual-licensing the IBM code contributions already present in U-Boot under either the terms of the GNU General Public License version 2, or the original code license already present.

This board is a dual processor board with each processor providing independent resources for Rapid IO, Gigabit Ethernet, and serial communications.

* ppc4xx: Consolidate PPC4xx UIC definesStefan Roese2008-07-11-708/+0
| | | | | | | | | | | | | | This 2nd patch now removes all UIC mask bit definition. They should be generated from the vectors by using the UIC_MASK() macro from now on. This way only the vectors need to get defined for new PPC's. Also only the really used interrupt vectors are now defined. This makes definitions for new PPC versions easier and less error prone. Another part of this patch is that the 4xx emac driver got a little cleanup, since now the usage of the interrupts is clearer. Signed-off-by: Stefan Roese <sr@denx.de>

* ppc4xx: Consolidate PPC4xx SDRAM/DDR/DDR2 defines, part1Stefan Roese2008-06-03-896/+0
| | | | | | | | | | | | | | | | | | | This patch removes all SDRAM related defines from the PPC4xx headers ppc405.h and ppc440.h. This is needed since now some 405 PPC's use the same SDRAM controller as 440 systems do (like 405EX and 440SP). It also introduces new defines for the equipped SDRAM controller based on which PPC variant is used. There new defines are: used on 405GR/CR/EP and some Xilinx Virtex boards. used on 440GP/GX/EP/GR. used on 440EPx/GRx. used on 405EX/r/440SP/SPe/460EX/GT. Signed-off-by: Stefan Roese <sr@denx.de>

* ppc4xx: Enable hardware-fix for PCI/DMA errata on AMCC 440SP/SPe boardsStefan Roese2007-12-06-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables the hardware-fix for the PCI/DMA errata's 19+22 by setting the FIXD bit in the SDR0_MFR register. Here a description of the symptoms: Problem Description ------------------------------ If a DMA is performed between memory and PCI with the DMA 1 Controller using prefetch, and as a result uses a special purpose buffer selected by the PCIXn Bridge Options 1 Register (PCIXn_BRDGOPT1[RBP7] - bits 31-29), the first part of the transfer sequence is performed twice. The PPC440SPe PCI Controller requests more data than was needed such that in the case of enforce memory protection, a host CPU exception can occur. No data is corrupted, because data transfer is stopped in the PCI Controller. Prefetch enable is specified by setting DMA Configuration Register (I2O0_DMAx_CFG[DXEPD] - bit 31) to 0. Behavior that may be observed in a running system --------------------------------------------------------------------------- 1. DMA performance is decreased because of the double access on the PCI bus interface. 2. If an illegal access to some address on the PCI bus is detected at the system level, a machine check or similar system error may occur. Workarounds Available ---------------------------------- 1. Do not program prefetch. Note that a prefetch command cannot be programmed without selecting a special purpose buffer. 2. To avoid crossing a physical boundary of the PCI slave device, add 512 bytes of address to the PCI address range. This patch was originally provided by Pravin M.
