| * Blackfin: fix up UART status bit handlingMike Frysinger2008-10-23-12/+60
| | | | | | | | | | | | | | | | Some Blackfin UARTs are read-to-clear while others are write-to-clear. This can cause problems when we poll the LSR and then later try and handle any errors detected. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
| * Blackfin: small cpu init optimization while setting interrupt maskMike Frysinger2008-10-23-5/+2
| | | | | | | | | | | | | | Use the sti instruction to set the initial interrupt mask rather than banging on the core IMASK MMR to save both space and time. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| * Blackfin: make baud calculation more accurateMike Frysinger2008-10-23-4/+4
| | | | | | | | | | | | | | | | We should use the algorithm in the Linux kernel so that the UART divisor calculation is more accurate. It also fixes problems on some picky UARTs that have sampling anomalies. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| * Blackfin: don't bother displaying reboot msg when crashingMike Frysinger2008-10-23-5/+1

| * Blackfin: enable support for nested interruptsMike Frysinger2008-10-23-4/+10

* | 74xx: use r4 instead of r2 in lock_ram_in_cache and unlock_ram_in_cacheDave Liu2008-10-31-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch is following the commit 392438406041415fe64ab8748ec5ab5ad01d1cf7 mpc86xx: use r4 instead of r2 in lock_ram_in_cache and unlock_ram_in_cache This is needed in unlock_ram_in_cache() because it is called from C and will corrupt the small data area anchor that is kept in R2. lock_ram_in_cache() is modified similarly as good coding practice, but is not called from C. Signed-off-by: Nick Spence <nick.spence@freescale.com> also, the r2 is used as global data pointer. Signed-off-by: Dave Liu <daveliu@freescale.com>

| * | 85xx: Fix the incorrect register used for DDR erratum1Dave Liu2008-10-24-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 8572 DDR erratum1: DDR controller may enter an illegal state when operating in 32-bit bus mode with 4-beat bursts. Description: When operating with a 32-bit bus, it is recommended that DDR_SDRAM_CFG[8_BE] is cleared when DDR2 memories are used. This forces the DDR controller to use 4-beat bursts when communicating to the DRAMs. However, an issue exists that could lead to data corruption when the DDR controller is in 32-bit bus mode while using 4-beat bursts. Projected Impact: If the DDR controller is operating in 32-bit bus mode with 4-beat bursts, then the controller may enter into a bad state. All subsequent reads from memory is corrupted. Four-beat bursts with a 32-bit bus only is used with DDR2 memories. Therefore, this erratum does not affect DDR3 mode. Work Arounds: To work around this issue, software must set DEBUG_1[31] in DDR memory mapped space (CCSRBAR offset + 0x2f00 for DDR_1 and CCSRBAR offset + 0x6f00 for DDR_2). Currenlty, the code is using incorrect register DDR_SDRAM_CFG_2 as condition, but it should be DDR_SDRAM_CFG register. Signed-off-by: Dave Liu <daveliu@freescale.com>

* | ppc4xx: Generic architecture for xilinx ppc405(v3)Ricardo Ribalda Delgado2008-10-24-1/+2
|/ | | | | | | | | | | | | | | | | As "ppc44x: Unification of virtex5 pp440 boards" did for the xilinx ppc440 boards, this patch presents a common architecture for all the xilinx ppc405 boards. Any custom xilinx ppc405 board can be added very easily with no code duplicity. This patch also adds a simple generic board, that can be used on almost any design with xilinx ppc405 replacing the file ppc405-generic/xparameters.h This patch is prepared to work with the latest version of EDK (10.1) Signed-off-by: Ricardo Ribalda Delgado <ricardo.ribalda@uam.es> Signed-off-by: Stefan Roese <sr@denx.de>

| * | ppc4xx: PPC44x MQ initializationYuri Tikhonov2008-10-17-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Set the MQ Read Passing & MCIF Cycle limits to the recommended by AMCC values. This fixes the occasional 440SPe hard locking issues when the 440SPe's dedicated DMA engines are used (e.g. by the h/w accelerated RAID driver). Previously the appropriate initialization had been made in Linux, by the ppc440spe ADMA driver, which is wrong because modifying the MQ configuration registers after normal operation has begun is not supported and could have unpredictable results. Comment from Stefan: This patch doesn't change the resulting value of the MQ registers. It explicitly sets/clears all bits to the desired state which better documents the resulting register value instead of relying on pre-set default values.
