* iop: unconditionally initialize the ATU on platforms known to be 'hosts'Dan Williams2008-03-26
| | | | | | | Platforms like iq80321 and iq80331 which may be host-bus-adapters require 'iop3xx_init_atu=y' to be specified on the kernel command line. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
* [ARM] 4476/1: EM7210/SS4000E supportArnaud Patard2007-07-20
| | | | | | | | This patch adds the basic support for the em7210 board. It is similar to the iq31244 board and can be found on Intel "Baxter Creek" ss4000e nas. Signed-off-by: Arnaud Patard <arnaud.patard@rtp-net.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] 4348/4: iop3xx: Give Linux control over PCI initializationDan Williams2007-05-03
| | | | | | | | | | | | | | | | | | | | | | | | | Currently the iop3xx platform support code assumes that RedBoot is the bootloader and has already initialized the ATU. Linux should handle this initialization for three reasons: 1/ The memory map that RedBoot sets up is not optimal (page_to_dma and virt_to_phys return different addresses). The effect of this is that using the dma mapping API for the internal bus dma units generates pci bus addresses that are incorrect for the internal bus. 2/ Not all iop platforms use RedBoot 3/ If the ATU is already initialized it indicates that the iop is an add-in card in another host, it does not own the PCI bus, and should not be re-initialized.

* [ARM] 4271/1: iop32x: fix ep80219 detection (support iq80219 platforms)Dan Williams2007-03-17
| | | | | | | | | | | | | An iq80219 is a board with an iq31244 layout and an 80219 processor. It breaks the current assumption that all 80219 processors run on ep80219 platforms. This patch adds the "force_ep80219" option to the kernel to override boot loaders that have passed in the iq31244 id, and adds the MACHINE_START definition for ep80219. [ patch assumes that EP80219 has been added to mach-types ] Signed-off-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [ARM] 3832/1: iop3xx: coding style cleanupLennert Buytenhek2006-09-25
| | | | | | | | | Since the iop32x code isn't iop321-specific, and the iop33x code isn't iop331-specfic, do a s/iop321/iop32x/ and s/iop331/iop33x/, and tidy up the code to conform to the coding style guidelines somewhat better.

* [ARM] 3830/1: iop3xx: board support file cleanupLennert Buytenhek2006-09-25
| | | | | | | | | | | Revamp the iop3xx board support: move the support code for each iop board type into its own file, start using platform serial and platform physmap flash devices, switch to a per-board time tick rate, and get rid of the ARCH_EP80219 and STEPD config options by doing the relevant checks at run time.
