| * ppc4xx: Add CFG_POST_ALT_WORD_ADDR to support non OCM POST WORD storageStefan Roese2008-01-09-1/+13
| | | | | | | | | | | | | | | | | | | | The privious 4xx POST implementation only supported storing the POST WORD in OCM. Since we need to reserve the OCM on LWMON5 for the logbuffer we need to store the POST WORD in some other non volatile location. This patch adds CFG_POST_ALT_WORD_ADDR to specify an address for such a location. Signed-off-by: Stefan Roese <sr@denx.de>
| * ppc4xx: Add 44x cache locking to better support init-ram in d-cacheStefan Roese2008-01-09-0/+52
| | | | | | | | | | | | | | | | | | | | | | This patch adds support for locking the init-ram/stack in d-cache, so that other regions may use d-cache as well Note, that this current implementation locks exactly 4k of d-cache, so please make sure that you don't define a bigger init-ram area. Take a look at the lwmon5 440EPx implementation as a reference. Signed-off-by: Stefan Roese <sr@denx.de>

| * | ppc4xx: Update Katmai/44x_spd_ddr2.c code for optimal DDR2 setupStefan Roese2008-01-05-15/+37
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | On Katmai the complete auto-calibration somehow doesn't seem to produce the best results, meaning optimal values for RQFD/RFFD. This was discovered by GDA using a high bandwidth scope, analyzing the DDR2 signals. GDA provided a fixed value for RQFD, so now on Katmai "only" RFFD is auto-calibrated. This patch also adds RDCC calibration as mentioned on page 7 of the AMCC PowerPC440SP/SPe DDR2 application note: "DDR1/DDR2 Initialization Sequence and Dynamic Tuning" Signed-off-by: Stefan Roese <sr@denx.de>
* | ppc4xx: Add functionality to GPIO supportLawrence R. Johnson2008-01-04-23/+40
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes two additions to GPIO support: First, it adds function gpio_read_in_bit() to read the a bit from the GPIO Input Register (GPIOx_IR) in the same way that function gpio_read_out_bit() reads a bit from the GPIO Output Register (GPIOx_OR). Second, it modifies function gpio_set_chip_configuration() to provide an additional option for configuring the GPIO from the "CFG_4xx_GPIO_TABLE". According to the 440EPx User's Manual, when an alternate output is used, the three-state control is configured in one of two ways, depending on the particular output. The first option is to select the corresponding alternate three-state control in the GPIOx_TRSH/L registers. The second option is to select the GPIO Three-State Control Register (GPIOx_TCR) in the GPIOx_TRSH/L registers, and set the corresponding bit in the GPIOx_TCR register to enable the output. For example, the Manual specifies configuring the GPIO00 Alternate 1 Signal (PreAddr07) to use the alternate three-state control (first option), and specifies configuring the GPIO32 Alternate 1 Signal (USB2OM0) with the output enabled in the GPIOx_TCR register (second option). Currently, gpio_set_chip_configuration() configures all alternate signal outputs to use the first option. This patch allow the second option to be selected by setting the "out_val" element in the table entry to "GPIO_OUT_1". The first option is used when the "out_val" element is set to "GPIO_OUT_0". Because "out_val" is not currently used when an alternate signal is selected, and because all current GPIO tables set "out_val" to "GPIO_OUT_0" for all alternate signals, this patch should not change any existing configurations.

* ppc4xx: Enable 405EP PCI arbiter per default on all boardsStefan Roese2007-12-28-0/+5
| | | | | | | | | | In an attmemt to clean up the 4xx start.S file, I removed the enabling of the internal 405EP PCI arbiter. This is needed for multiple other 405EP platforms, like most of the esd 405EP. Now the internal PCI arbiter is enabled again per default as it has been before.

* Add 440EPx DDR2 SPD DIMM supportLarry Johnson2007-12-27-0/+1254
| | | | | | | | | | | | | This patch adds SPD DDR2 support for the 440EPx ("Denali") SDRAM controller. It should also work on the 440GRx. It is based on the DDR2 SPD code for the 440EP/440EPx, but makes no provision for DDR1 support. This code has been tested on prototype Korat boards with three Kingston DIMMS: 512 MiB ECC (one rank), 512 MiB non-ECC (one rank) and 1 GiB ECC (two ranks). The Korat board has a single DIMM socket, but support has been provided (though not tested) for boards with two DIMM sockets. Signed-off-by: Larry Johnson <lrj@acm.org>
* Copy 440EPx/GRx SDRAM data-eye search to common directoryLarry Johnson2007-12-27-0/+396

* Add Ethernet 1000BASE-X support for PPC4xxLarry Johnson2007-12-27-52/+114
| | | | | | | | | | This patch adds a new switch: "CONFIG_PHY_DYNAMIC_ANEG". When this symbol is defined, the PHY will advertise it's capabilities for autonegotiation based on the capabilities shown in the PHY's status registers, including 1000BASE-X. When "CONFIG_PHY_DYNAMIC_ANEG" is not defined, the PHY will advertise hard-coded capabilities, as before. Signed-off-by: Larry Johnson <lrj@acm.org>
* ppc4xx: fdt: Cleanup setup of cpu node setupStefan Roese2007-12-27-3/+4
| | | | | | | | | Now the cpu node setup ("timebase-frequency" and "clock-frequency") is without using the absolute path to the cpu node. This makes it possible to use this U-Boot version with both versions of cpu-node naming "cpu@0" and the former "PowerPC,440EPx@0". Signed-off-by: Stefan Roese <sr@denx.de>

* ppc4xx: Make output a little shorter on I2C bootrom detectionStefan Roese2007-11-09-34/+19
| | | | | | | | | | | Most 4xx PPC capable of using an I2C bootrom for bootstrap setting already print a line with the information which I2C bootrom is used for bootstrap configuration. So we don't need this extra line with "I2C boot EEPROM en-/dis-abled". This patch also has a little code cleanup integrated. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Add CONFIG_4xx_DCACHE compile options to enable cached SDRAMStefan Roese2007-10-31-8/+5
| | | | | | | | | | | | | | This patch adds the CONFIG_4xx_DCACHE options to some SDRAM init files and to the Sequoia TLB init code. Now the cache can be enabled on 44x boards by defining CONFIG_4xx_DCACHE in the board config file. This option will disappear, when more boards use is successfully and no more known problems exist. This is tested successfully on Sequoia and Katmai. The only problem that needs to be fixed is, that USB is not working on Sequoia right now, since it will need some cache handling code too, similar to the 4xx EMAC driver.

* ppc4xx: Correct UART input clock calculation and passing to fdtStefan Roese2007-10-31-5/+7
| | | | | | | | We now use a value in the gd (global data) structure for the UART input frequency, since the PPC4xx_SYS_INFO struct is always rewritten completely in get_sys_info(). Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Add initial AMCC Haleakala PPC405EXr eval board supportStefan Roese2007-10-31-0/+10
| | | | | | | | | | The Haleakala is nearly identical with the Kilauea eval board. The only difference is that the 405EXr only supports one EMAC and one PCIe interface. This patch adds support for the Haleakala board by using the identical image for Kilauea and Haleakala. The distinction is done by comparing the PVR. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Rework of 4xx serial driver (4)Stefan Roese2007-10-31-167/+146
| | | | | | | | | | | | Change 4xx_uart.c: - Use in_8/out_8 macros instead of in8/out8 - No need for UART_BASE marco anymore, now really handled via function parameter - serial_init_common() introduced - Further coding style cleanup Signed-off-by: Stefan Roese <sr@denx.de>

| | | | | | | | | | This patch moves some common 4xx macros and the PPC405_SYS_INFO/ PPC440_SYS_INFO structure into the common ppc4xx.h header. Lot's of other macros are good candidates to be consolidated this way in the future. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Add PCIe endpoint support on Kilauea (405EX)Stefan Roese2007-10-31-10/+21
| | | | | | | | | | | | This patch adds endpoint support for the AMCC Kilauea eval board. It can be tested by connecting a reworked PCIe cable (only 1x lane singles connected) to another root-complex. In this test setup, a 64MB inbound window is configured at BAR0 which maps to 0 on the PLB side. So accessing this BAR0 from the root-complex will access the first 64MB of the SDRAM on the PPC side.

* ppc4xx: Dynamic configuration of 4xx PCIe mode as root or endpoint modeStefan Roese2007-10-31-1/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for dynamic configuration of PCIe ports for the AMCC PPC4xx boards equipped with PCIe interfaces. These are the PPC440SPe boards Yucca & Katmai and the 405EX board Kilauea. This dynamic configuration is done via the "pcie_mode" environement variable. This variable can be set to "EP" or "RP" for endpoint or rootpoint mode. Multiple values can be joined via the ":" delimiter. Here an example: pcie_mode=RP:EP:EP This way, PCIe port 0 will be configured as rootpoint, PCIe port 1 and 2 as endpoint. Per default Yucca will be configured as: pcie_mode=RP:EP:EP Per default Katmai will be configured as: pcie_mode=RP:RP:REP Per default Kilauea will be configured as: pcie_mode=RP:RP Signed-off-by: Tirumala R Marri <tmarri@amcc.com> Signed-off-by: Stefan Roese <sr@denx.de>
