This patch adds a BSP variant for the Raspberry Pi 2. You can
build both variants by configuring with the option
--enable-rtemsbsp="raspberrypi2 raspberrypi"
For the current BSP, the only change was the peripheral register base
address and the compiler options.
The raspberrypi/make/custom rules were re-factored:
raspberrypi.inc -- Common rules
raspberrypi.cfg -- Raspberry Pi 1 specific rule/optons
raspberrypi2.cfg -- Raspberry Pi 2 specific rule/options
I tested hello, ticker, unlimited, and paranoia on both the Pi (Model A+)
and Pi 2.
Deprecate Classic API Notepads. Mark task_set/get_note() with
the deprecated attribute, and also mark the notepads field.
Replace disable with enable option for notepads in confdefs.h,
and make notepads disabled by default. The previous option
CONFIGURE_DISABLE_CLASSIC_API_NOTEPADS is now unused and
will emit a compile-time warning. A new option
CONFIGURE_ENABLE_CLASSIC_API_NOTEPADS is available to turn
on notepads, but it also will emit a compile-time warning
to indicate that notepads are deprecated.
Closes#2265
These header files were only used by one BSP and they are
hardware dependent. The hardware dependency always made
them bad candidates for where they were in the tree. But
this fixes that.
Some BSPs have issues linking the dl* tests. These issues have
not been investigated. This is a temporary workaround until we
have an explanation and permanent solution.
updates 2258.
This patch adds the macro BSP_START_NEEDS_REGISTER_INITIALIZATION and
three hooks for BSP-specific register init code to arm/shared/start.S.
Said hooks are bsp_start_init_registers_core (intended for initializing
the ARM core registers), bsp_start_init_registers_banked_fiq (for the
FIQ mode banked registers) and bsp_start_init_registers_vfp (for the FPU
registers). BSP_START_NEEDS_REGISTER_INITIALIZATION would be defined in
a BSP's configure.ac (so that it appears in its bspopts.h).
This patch also adds the register init code required by the TMS570.
We've tested it with the tms570ls3137_hdk.cfg config and it works fine.
This patch allows the existing FPU code to support both VFP-D16 and
VFP-D32. According to ARM, writes to D32DIS are ignored for D16 so
there's no need to enclose the bic instruction with an #ifdef. We tested
it on a TMS570LS3137 using TI initialization code and it works fine.

Remove miniIMFS. Statically initialize the root IMFS.
Add configuration options to disable individual
features of the root IMFS, e.g.
o CONFIGURE_IMFS_DISABLE_CHOWN,
o CONFIGURE_IMFS_DISABLE_FCHMOD,
o CONFIGURE_IMFS_DISABLE_LINK,
o CONFIGURE_IMFS_DISABLE_MKNOD,
o CONFIGURE_IMFS_DISABLE_MOUNT,
o CONFIGURE_IMFS_DISABLE_READLINK,
o CONFIGURE_IMFS_DISABLE_RENAME,
o CONFIGURE_IMFS_DISABLE_RMNOD,
o CONFIGURE_IMFS_DISABLE_SYMLINK,
o CONFIGURE_IMFS_DISABLE_UNMOUNT, and
o CONFIGURE_IMFS_DISABLE_UTIME.
This allows it to be wrapped by another function at link-time
and can be used to trace interrupts. If not placed in a separate
file, the function pointer address used in BSP_shared_interrupt_init
will be resolved at compile-time, and the function will not be wrappable.
The structure tms570_sci_context holds state variable
tx_chars_in_hw which holds if and how many characters
(in the optional FIFO support for some Ti SCIs) are submitted
into hardware.
When field is not writable then code breaks when RTEMS
is build for Flash area.
