2012-10-15serial: mpc512x: Move serial registration from serial_initialize()Marek Vasut
Move the registration of serialN_device ports from default serial_initialize() into driver specific function called from serial_initialize(). This slims down the serial_initialize() call to a bare tracker of all possible serial port registration routines in U-Boot. The newly implemented mpc512x_serial_initialize() function, which is implemented inside of the mpc512x serial driver allows encapsulation of serialN_device within the mpc512x serial driver itself. Also, remove the exports of serialN_device from include/serial.h as they are no longer needed. This is simply because the implementation of default_serial_console() is wrapped into the mpx512x serial driver and the default console is picked by CONFIG_SERIAL<N> macro in config file.

2012-09-02powerpc: re-add bi_ip_addr to bd_t structAnatolij Gustschin
Since commit 50a47d0523e8efebe912bef539a77ffd42116451 (net: punt bd->bi_ip_addr) booting old 2.4.x ppc kernels is broken due to changed offsets of the fields in struct bd_t. Offsets of the fields after removed bi_ip_addr are wrong, causing wrong bus clocks and console baudrate configurations and various other issues. Re-add the bi_ip_addr field to preserve backward compatibility with older ppc kernels. Setting bi_ip_addr in board.c is not really needed, grepping in the 2.4 linux tree shows that bi_ip_addr is not accessed there. Adding bi_ip_addr to struct bd_t for other arches isn't needed it seems. bd_t is not used by other arches in the 2.4 linux tree.

2012-08-23powerpc/fsl-corenet: work around erratum A004510Scott Wood
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.

2012-08-23powerpc/corenet_ds: Master module for boot from PCIELiu Gang
For the powerpc processors with PCIE interface, boot location can be configured from one PCIE interface by RCW. The processor booting from PCIE can do without flash for u-boot image. The image can be fetched from another processor's memory space by PCIE link connected between them. The processor booting from PCIE is slave, the processor booting from normal flash memory space is master, and it can help slave to boot from master's memory space. When boot from PCIE, slave's core should be in holdoff after powered on for some specific requirements. Master will release the slave's core at the right time by PCIE interface. Environment and requirement: master: 1. NOR flash for its own u-boot image, ucode and ENV space. 2. Slave's u-boot image is in master NOR flash. 3. Normally boot from local NOR flash. 4. Configure PCIE 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 one PCIE interface by RCW. 3. RCW should configure the SerDes, PCIE interfaces correctly. 4. Must set all the cores in holdoff by RCW. 5. Must be powered on before master's boot. For the master module, need to finish these processes: 1. Initialize the PCIE port and address space. 2. Set inbound PCIE windows covered slave's u-boot image stored in master's NOR flash. 3. Set outbound windows in order to configure slave's registers for the core's releasing. 4. Should set the environment variable "bootmaster" to "PCIE1", "PCIE2" or "PCIE3" using the following command: setenv bootmaster PCIE1 saveenv Signed-off-by: Liu Gang <Gang.Liu@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>

When compile the slave image for boot from SRIO, no longer need to specify which SRIO port it will boot from. The code will get this information from RCW and then finishes corresponding configurations. This has the following advantages: 1. No longer need to rebuild an image when change the SRIO port for boot from SRIO, just rewrite the new RCW with selected port, then the code will get the port information by reading new RCW. 2. It will be easier to support other boot location options, for example, boot from PCIE. Signed-off-by: Liu Gang <Gang.Liu@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>

Reduce a build configuration item in boards.cfg file. No longer need to build a special image for master, just use a normal target image and set the "bootmaster" variable. 2. No longer need to rebuild an image when change the SRIO port for boot from SRIO, just set the corresponding value to "bootmaster" based on the using SRIO port.
