2007-11-21Blackfin arch: cplb and map header file cleanupMike Frysinger
- remove duplicated defines for the BF561 - generalize L2 support (so that it works for BF54x) and mark it executable - add support for reading/executing the Boot ROM sections (since it has data/functions we may need at runtime) - and fixup names for each map Signed-off-by: Mike Frysinger <michael.frysinger@analog.com> Signed-off-by: Bryan Wu <bryan.wu@analog.com>

2007-11-21Blackfin arch: add support for working around anomaly 05000312Mike Frysinger
Anomaly 05000312 - Errors When SSYNC, CSYNC, or Loads to LT, LB and LC Registers Are Interrupted: DESCRIPTION: When instruction cache is enabled, erroneous behavior may occur when any of the following instructions are interrupted: . CSYNC • SSYNC • LCx = • LTx = (only when LCx is non-zero) • LBx = (only when LCx is non-zero) When this problem occurs, a variety of incorrect things could happen, including an illegal instruction exception. Additional errors could show up as an exception, a hardware error, or an instruction that is valid but different than the one that was expected. WORKAROUND: Place a cli before all SSYNC, CSYNC, "LCx =", "LTx =", and "LBx =" instructions to disable interrupts, and place an sti after each of these instructions to re-enable interrupts. When these instructions are executed in code that is already non-interruptible, the problem will not occur.

2007-11-18Blackfin arch: fix bug kernel not to boot up with mtd filesystemsBernd Schmidt
Revert this patch: move the init sections to the end of memory, so that after they are free, run time memory is all continugous - this should help decrease memory fragementation. When doing this, we also pack some of the other sections a little closer together, to make sure we don't waste memory. To make this happen, we need to rename the .data.init_task section to .init_task.data, so it doesn't get picked up by the linker script glob. Since it causes the kernel not to boot up with mtd filesystems. Signed-off-by: Bernd Schmidt <bernd.schmidt@analog.com> Signed-off-by: Bryan Wu <bryan.wu@analog.com>

2007-11-17Blackfin arch: Add assembly function insl_16Michael Hennerich
/* * CPUs often take a performance hit when accessing unaligned memory * locations. The actual performance hit varies, it can be small if the * hardware handles it or large if we have to take an exception and fix * it * in software. * * Since an ethernet header is 14 bytes network drivers often end up * with * the IP header at an unaligned offset. The IP header can be aligned by * shifting the start of the packet by 2 bytes. Drivers should do this * with: * * skb_reserve(NET_IP_ALIGN); * * The downside to this alignment of the IP header is that the DMA is * now * unaligned. On some architectures the cost of an unaligned DMA is high * and this cost outweighs the gains made by aligning the IP header. * * Since this trade off varies between architectures, we allow * NET_IP_ALIGN * to be overridden. */ This new function insl_16 allows to read form 32-bit IO and writes to 16-bit aligned memory. This is useful in above described scenario - In particular with the AXIS AX88180 Gigabit Ethernet MAC. Once the device is in 32-bit mode, reads from the RX FIFO always decrements 4bytes. While on the other side the destination address in SDRAM is always 16-bit aligned. If we use skb_reserve(0) the receive buffer is 32-bit aligned but later we hit a unaligned exception in the IP code.
