* powerpc/mpc85xx/p1_p2_rdb: add all LAWs during SPLScott Wood2012-08-23-2/+0
| | | | | | | | | | | | | | | | | | | LAW init is skipped in the SPL payload because it's assumed that the SPL has taken care of it -- so make sure the SPL loads all the LAWs as is done on other boards. This bug was introduced by: commit 4589728e214958a4e6e011a081a68d360c49d7a5 Author: Kumar Gala <galak@kernel.crashing.org> Date: Fri Nov 11 08:14:53 2011 -0600 powerpc/85xx: Fix builds of P1020/P2020RDB-PC_36BIT_NAND Size grew a bit so nand-spl didn't fit in 4k, reduce done by removing LAW entries not needed during SPL phase.

* powerpc/p1_p2_rdb_pc: print -PC suffix in board nameScott Wood2012-08-23-5/+5
| | | | | | | | | | | | | | | | Currently the -PC variants of the P1/P2 RDB boards do not print it on boot -- e.g. a P2020RDB-PC will claim to be a plain P2020RDB. Besides being incorrect, this can confuse a user into building U-Boot for P2020RDB rather than P2020RDB-PC, resulting in a board that does not boot. P1024RDB and P1025RDB are not included, as these boards apparently do not have -PC as part of their name, even though they are supported by p1_p2_rdb_pc. The P2020RDB variant covered by this is apparently P2020RDB-PCA rather than P2020RDB-PC. Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>

* powerpc/fsl-corenet: work around erratum A004510Scott Wood2012-08-23-0/+355
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* powerpc/corenet_ds: Slave module for boot from PCIELiu Gang2012-08-23-49/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Slave's ucode and ENV can be stored in master's memory space, then slave can fetch them through PCIE interface. For the corenet platform, ucode is for Fman. NOTE: Because the slave can not erase, write master's NOR flash by PCIE interface, so it can not modify the ENV parameters stored in master's NOR flash using "saveenv" or other commands. 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. Put the slave's ucode and ENV into it's own memory space. 4. Normally boot from local NOR flash. 5. 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 slave module, need to finish these processes: 1. Set the boot location to one PCIE interface by RCW. 2. Set a specific TLB entry for the boot process. 3. Set a LAW entry with the TargetID of one PCIE for the boot. 4. Set a specific TLB entry in order to fetch ucode and ENV from master. 5. Set a LAW entry with the TargetID one of the PCIE ports for ucode and ENV. 6. Slave's u-boot image should be generated specifically by make xxxx_SRIO_PCIE_BOOT_config. This will set SYS_TEXT_BASE=0xFFF80000 and other configurations. In addition, the processes are very similar between boot from SRIO and boot from PCIE. Some configurations like the address spaces can be set to the same. So the module of boot from PCIE was added based on the existing module of boot from SRIO, and the following changes were needed: 1. Updated the README.srio-boot-corenet to add descriptions about boot from PCIE, and change the name to README.srio-pcie-boot-corenet. 2. Changed the compile config "xxxx_SRIOBOOT_SLAVE" to "xxxx_SRIO_PCIE_BOOT", and the image builded with "xxxx_SRIO_PCIE_BOOT" can support both the boot from SRIO and from PCIE. 3. Updated other macros and documents if needed to add information about boot from PCIE. Signed-off-by: Liu Gang <Gang.Liu@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For the powerpc processors with PCIE interface, boot location can be configured from one PCIE interface by RCW.

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.

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.

* powerpc: Stack Pointer not properly alignedJoakim Tjernlund2012-08-22-3/+2
| | | | | | | | | The code first aligns the SP to 16 then subtract 8, making it 8 bytes aligned. Furthermore the initial stack frame not quite correct either. Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se> Signed-off-by: Andy Fleming <afleming@freescale.com>
* mpc85xx: Initial SP alignment is wrong.Joakim Tjernlund2012-08-22-11/+5
| | | | | | | | | | | | PowerPC mandates SP to be 16 bytes aligned. Furthermore, a stack frame is added, pointing to the reset vector which may in the way when gdb is walking the stack because the reset vector may not accessible depending on emulator settings. Also use a temp register so gdb doesn't pick up intermediate values.

* mtd/cfi_flash: fix write problems for Numonyx P33/30 32 MBit flashsHolger Brunck2012-08-13-22/+44
| | | | | | | | | | | | | | | | | | commit 54652991 Work around bug in Numonyx P33/P30 256-Mbit 65nm flash chips fixes a problem for Numonyx P33/P30 flashes for 256-Mbit, but this leads to problems for smaller versions of this chip e.g. the 32Mbit version with deviceid 0x16 on mgcoge. So move the code for this work around to an own function and check previously manufacturer id and device id to not break other flashes which don't need this work around.
