|
// NOTE: In some ROMs between 3.0 and 3.3 (inclusive), OEMs may have
|
|
// ROM tokens present in the ROM that were detected by the boot code
|
|
// in order to set the various HwrMiscFlags and GHwrMiscFlagsExt
|
|
// settings. That scheme is no longer relevant, since starting with
|
|
// version 3.5 and later, it is now the responsibility of the HAL
|
|
// to set these flags, using whatever means necessary to determine
|
|
// what "features" the device has that the higher level OS may want
|
|
// to know about.
|
|
//
|
|
// These flags are defined in this public header file since both
|
|
// of these low memory globals are published as system features
|
|
// (sysFtrNumHwrMiscFlags and sysFtrNumHwrMiscFlagsExt) in <SystemMgr.h>.
|
|
// These features are for third party software that may (for whatever
|
|
// reason) want to know about certain hardware differences without
|
|
// having to read the low memory globals directly.
|
|
//
|
|
// Palm OS v3.1 was the first OS to publish sysFtrNumHwrMiscFlags as a feature.
|
|
// Call FtrGet first; if the feature doesn't exist, check the OS version:
|
|
// Palm OS v2.0 and 3.0 have GHwrMiscFlags defined as a low memory global.
|
|
// Palm OS v1.0 did not have GHwrMiscFlags, so its contents are unpredictable.
|
|
// Any devices running Palm OS v1.0 devices should assume zero for all flags.

// NOTE: Currently, the '328 IDs don't overlap with the 'EZ IDs. This is NOT a requirement,
|
|
// but is convenient for the time being as it makes it one step easier to identify a device.
|
|
// If the spaces are forced to overlap, it will be necessary to first check the processor
|
|
// type (328 or EZ) and then parse the product ID code. Fortunately, this scheme is rapidly
|
|
// becoming obsolete since it was based on reading the keyboard I/O pins, and new products
|
|
// are starting to move their keyboard I/O bits to new places. With the introduction of
|
|
// different HAL modules, identifying the actual hardware is now something the HAL code
|
|
// will do when the device boots. The HAL need only do whatever it needs to do to uniquely
|
|
// tell the difference between those devices on which it is capable of operating. Once
|
|
// the hardware is identified, the appropriate hwrMiscFlag and hwrMiscFlagExt bits can be
|
|
// set to tell the OS what features are present, and the appropriate hardware ID information
|
|
// can also be set so higher level software can uniquely identify the OEM/Device/HAL info.

// 3/16/99 SCL: Documented '328 and 'EZ IDs and how the space could overlap if necessary
