f9648baf65 bsps/arm: Add support for small pages MMU 
The small page MMU support reduces the granularity for memory settings
through the MMU from 1MiB sections to 4KiB small pages.

f462bcbb0a riscv: Address differences in the linkerscript between GNU LD and LLVM/LLD 
LLVM/LLD does not support STARTUP and ALIGN_WITH_INPUT directives that
GNU LD support. INPUT and ALIGN(8) are supported by LLVM/LLD and can
replace the unsupported STARTUP/ALIGN_WITH_INPUT directives.

The commit conditionally adds the supported directive that linkers
can understand depending on the toolchain used to compile RTEMS
i.e., clang or gcc. Clang is assumed to use LLD by default.

d4b92da208 bsps/atsam: Improve case for level triggered IRQs. 
For level triggered interrupts currently the handler would have been
called two times (assuming no one cleared the mask in a handler which
would have been bad because the handler couldn't process all other that
got cleared by accident). This patch allows the handler only to return
if nothing is left to do.

33ed4123c0 rtems: Add rtems_interrupt_server_entry_move() 
The use case for this function is the libbsd.  In FreeBSD, the interrupt
setup and binding to a processor is done in two steps.  Message
based interrupts like PCIe MSI and MSI-X interrupts can be implemented
through interrupt server entries.  They are setup at the default
interrupt server and may optionally move to an interrupt server bound to
a specific processor.

c331bdc777 record: Allow tracing of ISR disable/enable 
Directly use the CPU port API in boot_card() to allow tracing of the
higher level interrupt disable/enable routines, e.g.
_ISR_Local_disable() and _ISR_Local_enable().  Currently, there is no
configuration option to enable this.  Below is a patch.  It may be used
to investigate some nasty low level bugs in the system.

Update #3665.

b89d6cc5e4 bsp/beagle: Partial re-write of I2C driver. 
The old driver worked well for EEPROMS with the RTEMS EEPROM driver. But
it had problems with a lot of other situations. Although it's not a
direct port, the new driver is heavily modeled after the FreeBSD ti_i2c
driver.
