2013-03-07hw/nand.c: correct the sense of the BUSY/READY status bitKuo-Jung Su
The BIT6 of Status Register(SR): SR[6] behaves the same as R/B# pin SR[6] = 0 indicates the device is busy; SR[6] = 1 means the device is ready Some NAND flash controller (i.e. ftnandc021) relies on the SR[6] to determine if the NAND flash erase/program is success or error timeout. P.S: The exmaple NAND flash datasheet could be found at following link: http://www.mxic.com.tw/QuickPlace/hq/PageLibrary4825740B00298A3B.nsf/h_Index/8FEA549237D2F7674825795800104C26/$File/MX30LF1G08AA,%203V,%201Gb,%20v1.1.pdf Signed-off-by: Kuo-Jung Su <dantesu@gmail.com> Reviewed-by: Peter Crosthwaite <peter.crosthwaite@xilinx.com> Signed-off-by: Edgar E.

2013-01-21sysbus: Drop sysbus_from_qdev() cast macroAndreas Färber
Replace by SYS_BUS_DEVICE() QOM cast macro using a scripted conversion. Avoids the old macro creeping into new code. Resolve a Coding Style warning in openpic code.

2013-01-10Make all static TypeInfos constAndreas Färber
Since 39bffca2030950ef6efe57c2fac8327a45ae1015 (qdev: register all types natively through QEMU Object Model), TypeInfo as used in the common, non-iterative pattern is no longer amended with information and should therefore be const. Fix the documented QOM examples: sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h Since frequently the wrong examples are being copied by contributors of new devices, fix all types in the tree: sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c This also avoids to piggy-back these changes onto real functional changes or other refactorings.

2012-02-15qom: Unify type registrationAndreas Färber
Replace device_init() with generalized type_init(). While at it, unify naming convention: type_init([$prefix_]register_types) Also, type_init() is a function, so add preceding blank line where necessary and don't put a semicolon after the closing brace.

2012-02-03qdev: register all types natively through QEMU Object ModelAnthony Liguori
This was done in a mostly automated fashion. I did it in three steps and then rebased it into a single step which avoids repeatedly touching every file in the tree. The first step was a sed-based addition of the parent type to the subclass registration functions. The second step was another sed-based removal of subclass registration functions while also adding virtual functions from the base class into a class_init function as appropriate. Finally, a python script was used to convert the DeviceInfo structures and qdev_register_subclass functions to TypeInfo structures, class_init functions, and type_register_static calls. We are almost fully converted to QOM after this commit. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

First step cleaning up the drives handling. This one does nothing but removing drives_table[], still it became seriously big. drive_get_index() is gone and is replaced by drives_get() which hands out DriveInfo pointers instead of a table index.
