* tegra20: add USB ULPI init codeLucas Stach2012-10-15-0/+3
| | | | | | | | | | | | | This adds the required code to set up a ULPI USB port. It is mostly a port of the Linux ULPI setup code with some tweaks added for more correctness, discovered along the way of debugging this. To use this both CONFIG_USB_ULPI and CONFIG_USB_ULPI_VIEWPORT have to be set in the board configuration file.

* Add a command to access the system timerJoe Hershberger2012-10-03-1/+2
| | | | | | | | | | Two sub-commands... start and get. * start sets the reference. * get prints out the time since the last start (in "<sec>.<msec>" format). If get is called without start, returns time since boot. Simple way to benchmark an operation: "timer start;<commands-to-measure>;timer get" Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>

* SPL: Move the omap SPL framework to common/splTom Rini2012-09-27-0/+5
| | | | | | | | | | | | | Add a new flag, CONFIG_SPL_FRAMEWORK to opt into the common/spl SPL framework, enable on all of the previously using boards. We move the spl_ymodem.c portion to common/ and spl_mmc.c to drivers/mmc/. We leave the NAND one in-place as we plan to replace it later in this series. We use common/spl to avoid linker problems with respect to merging constant strings in objects. Otherwise all strings in common/ will be linked in and kept which grows SPL in size too much.

| * powerpc/fsl-corenet: work around erratum A004510Scott Wood2012-08-23-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Erratum A004510 says that under certain load conditions, modified cache lines can be discarded, causing data corruption. To work around this, several CCSR and DCSR register updates need to be made in a careful manner, so that there is no other transaction in corenet when the update is made. The update is made from a locked cacheline, with a delay before to flush any previous activity, and a delay after to flush the CCSR/DCSR update. We can't use a readback because that would be another corenet transaction, which is not allowed. We lock the subsequent cacheline to prevent it from being fetched while we're executing the previous cacheline. It is filled with nops so that a branch doesn't cause us to fetch another cacheline. Ordinarily we are running in a cache-inhibited mapping at this point, so we temporarily change that. We make it guarded so that we should never see a speculative load, and we never do an explicit load. Thus, only the I-cache should ever fill from this mapping, and we flush/unlock it afterward. Thus we should avoid problems from any potential cache aliasing between inhibited and non-inhibited mappings. NOTE that if PAMU is used with this patch, it will need to use a dedicated LAW as described in the erratum. This is the responsibility of the OS that sets up PAMU.

| | | | | | | | | | | | | | | | | | | | | | Introduce CONFIG_PCI_ENUM_ONLY variable for platforms that just want a quick enumberation of the PCI devices, but don't need any setup work done. This is very beneficial on platforms that have u-boot loaded by another boot loader which does a more sophisticated job of setup of PCI devices than u-boot. That way, u-boot can just read what's there and get on with life. This is what SeaBIOS does. Signed-off-by: Andrew Sharp <andywyse6@gmail.com>

| * powerpc/corenet_ds: Slave reads ENV from master when boot from SRIOLiu Gang2012-04-24-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When boot from SRIO, slave's ENV can be stored in master's memory space, then slave can fetch the ENV through SRIO interface. NOTE: Because the slave can not erase, write master's NOR flash by SRIO interface, so it can not modify the ENV parameters stored in master's NOR flash using "saveenv" or other commands. Master needs to: 1. Put the slave's ENV into it's own memory space. 2. Set an inbound SRIO window covered slave's ENV stored in master's memory space. Slave needs to: 1. Set a specific TLB entry in order to fetch ucode and ENV from master. 2. Set a LAW entry with the TargetID SRIO1 or SRIO2 for ucode and ENV.

| * powerpc/corenet_ds: Slave module for boot from SRIOLiu Gang2012-04-24-0/+6

The processor booting from SRIO can do without flash for u-boot image. The image can be fetched from another processor's memory space by SRIO link connected between them. The processor boots from SRIO is slave, the processor boots from normal flash memory space and can help slave to boot from its memory space is master. They are different environments and requirements: master: 1. NOR flash for its own u-boot image, ucode and ENV space. 2. Slave's u-boot image in master NOR flash. 3. Normally boot from local NOR flash. 4. Configure SRIO switch system if needed. slave: 1. Just has EEPROM for RCW. No flash for u-boot image, ucode and ENV. 2. Boot location should be set to SRIO1 or SRIO2 by RCW. 3. RCW should configure the SerDes, SRIO interfaces correctly. 4. Slave must be powered on after master's boot. 5. Must define CONFIG_SYS_QE_FMAN_FW_IN_REMOTE because of no ucode locally. For the slave module, need to finish these processes: 1. Set the boot location to SRIO1 or SRIO2 by RCW. 2. Set a specific TLB entry for the boot process. 3. Set a LAW entry with the TargetID SRIO1 or SRIO2 for the boot. 4. Slave's u-boot image should be generated specifically by make xxxx_SRIOBOOT_SLAVE_config. This will set SYS_TEXT_BASE=0xFFF80000 and other configurations.

* common/image.c: align usage of fdt_high with initrd_highShawn Guo2012-02-27-0/+8
| | | | | | | | | | | | | | | | | | The commit message of a28afca (Add uboot "fdt_high" enviroment variable) states that fdt_high behaves similarly to the existing initrd_high. But fdt_high actually has an outstanding difference from initrd_high. The former specifies the start address, while the later specifies the end address. As fdt_high and initrd_high will likely be used together, it'd be nice to have them behave same. The patch changes the behavior of fdt_high to have it aligned with initrd_high. The document of fdt_high in README is updated with an example to demonstrate the usage of this environment variable.

| | | | | | | | The BAB7xx boards are almost deceased. They cause build warnings, an it's not worth the effort to fix these. Remove the dead body. Signed-off-by: Wolfgang Denk <wd@denx.de> Cc: Frank Gottschling <fgottschling@eltec.de>
* Introduce generic TPM support in u-bootVadim Bendebury2011-12-07-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TPM (Trusted Platform Module) is an integrated circuit and software platform that provides computer manufacturers with the core components of a subsystem used to assure authenticity, integrity and confidentiality. This driver supports version 1.2 of the TCG (Trusted Computing Group) specifications. The TCG specification defines several so called localities in a TPM chip, to be controlled by different software layers. When used on a typical x86 platform during the firmware phase, only locality 0 can be accessed by the CPU, so this driver even while supporting the locality concept presumes that only locality zero is used. This implementation is loosely based on the article "Writing a TPM Device Driver" published on http://ptgmedia.pearsoncmg.com Compiling this driver with DEBUG defined will generate trace of all accesses to TMP registers. This driver has been tested and is being used in three different functional ChromeOS machines (Pinetrail and Sandy Bridge Intel chipsets) all using the same Infineon SLB 9635 TT 1.2 device. A u-boot cli command allowing access to the TPM was also implemented and is being submitted as a second patch.

* powerpc/85xx: clean up and document the QE/FMAN microcode macrosTimur Tabi2011-11-29-0/+38
| | | | | | | | | | | | | | | | | | | | Several macros are used to identify and locate the microcode binary image that U-boot needs to upload to the QE or Fman. Both the QE and the Fman use the QE Firmware binary format to package their respective microcode data, which is why the same macros are used for both. A given SOC will only have a QE or an Fman, so this is safe. Unfortunately, the current macro definition and usage has inconsistencies. For example, CONFIG_SYS_FMAN_FW_ADDR was used to define the address of Fman firmware in NOR flash, but CONFIG_SYS_QE_FW_IN_NAND contains the address of NAND. There's no way to know by looking at a variable how it's supposed to be used. In the future, the code which uploads QE firmware and Fman firmware will be merged.
