[PATCH 00/30] LEON improvements, second batch

Second batch of patches for LEON. Focus this time on the two multi-core LEON chips, GR712RC and GR740. In short it contains: * GR740 quad-core LEON4-FT BSP updates, new drivers specific for GR740: - I/O MMU bit access vector protection - LEON4 statistics counters - Main memory scrubber

[PATCH 05/30] leon, clock: new driver manager clock driver

From: Martin Aberg - Compatible with SMP - Selects timecounter depending on features available - Fixes problem with time going to fast on SMP This is an implementation of the RTEMS "clockdrv_shell" interface for LEON2/3/4 systems using the Driver Manager. It is clock hardware agnostic and compat

[PATCH 08/30] leon, apbuart: RX delayed interrupt

From: Martin Aberg Utilize the APBUART RX delayed interrupt if available. It also enables RX FIFO interrupt when used. The APBUART RX delayed interrupt is supported by the GR740. --- c/src/lib/libbsp/sparc/shared/uart/apbuart_cons.c | 44 +-- 1 file changed, 42 insertions(+)

[PATCH 13/30] leon, apbuart: Wait for shift register on close

From: Martin Aberg Do not disable transmitter until shift register is empty when closing device. It is correct to look at the sending software state when closing the device. However, the sending state must be cleared only when everything is sent. --- c/src/lib/libbsp/sparc/shared/uart/apbuart_co

[PATCH 11/30] leon, apbuart: support termios task driven mode

From: Martin Aberg The APBUART control register can be updated from both ISR and task context so the device must be locked when manipulating the register. There is also a scenario with RX FIFO interrupts where a few characters can be in the FIFO without generating interrupt. --- c/src/lib/libbsp

[PATCH 12/30] leon, apbuart: Optimized RX processing in ISR

From: Martin Aberg Limit the number of calls to termios rtems_termios_enqueue_raw_characters() by reading out the RX FIFO on stack and then call termios only once. --- c/src/lib/libbsp/sparc/shared/uart/apbuart_cons.c | 25 +++ 1 file changed, 17 insertions(+), 8 deletions(-)

[PATCH 07/30] leon, cons: drvmgr cons interface uses new TERMIOS

From: Martin Aberg LEON driver manager console driver interface (cons) and the APBUART cons driver (apbuart_cons) have been updated for recent TERMIOS interface changes. The legacy callback API is not used anymore and deprecated functions are eliminated. This new implementation is based on RTEMS

[PATCH 06/30] leon, apbuart: added register defines: FIFO, delay int

From: Martin Aberg The FIFOs available capability bit is available in the UART Control Register: FIFOs available (FA) - Set to 1 when receiver and transmitter FIFOs are available. When 0, only holding register is available. Delay interrupt can delay a receive character interrupt to better handle
