* src/nano_misc.c: Replaced explicit prototype of memset with
|
| 3 |
|
|
#include .
|

|
|
2002-08-12 Mark Salter

|
|
|

|
|
* misc/redboot_POST.ecm: Remove CYGSEM_REDBOOT_ARM_LINUX_BOOT.
|
| 8 |
|
|
* misc/redboot_RAM.ecm: Ditto.

|
| 11 |
|
|
|

|
| 15 |
|
|
|
| 16 |
|
|
* cdl/hal_arm_sa11x0_nano.cdl:
|
| 17 |
|
|
Standardize CYGNUM_HAL_VIRTUAL_VECTOR_CONSOLE_CHANNEL_DEFAULT usage.
|
| 18 |

2002-03-06 Jesper Skov
|

|
|
|
| 21 |
|
|
* misc/redboot_RAM.ecm: Updated. Added zlib.
|
| 22 |
|
|
* misc/redboot_ROM.ecm: Same.

2002-01-30 Jonathan Larmour
|
| 25 |
|
|
|
| 26 |
|
|
* include/nano.h (HAL_PCI_DO_CONFIG_ACCESS): If requesting vendor
|
| 27 |
|
|
config, check it isn't 0 or 256 which would be bogus - instead
|
| 28 |
|
|
this indicates the device is absent, e.g. the second eth controller
|
| 29 |
|
|
that is found on the commEngine, but not on the nanoEngine.
|
| 30 |

|
2002-01-28 Jesper Skov
|
| 32 |
|
|
|
| 33 |
|
|
* include/plf_io.h: Added.
|
| 34 |
|
|
|
| 35 |
|
|
* cdl/hal_arm_sa11x0_nano.cdl: Remove explicit plf_io.h
|
| 36 |
|
|
declaration.
|
| 37 |
|
|
|
| 38 |
|
|
2001-05-02 Hugo Tyson
|
| 39 |
|
|
|
| 40 |
|
|
* src/nano_misc.c (hal_mmu_init): Set up PCI memory in the new
|
| 41 |
|
|
location, where it will not already be mapped by the default
|
| 42 |
|
|
layout. This requires "stealing" RAM from the linear layout.
|
| 43 |
|
|
It's done this way so that a RAM app will work OK atop an
|
| 44 |
|
|
old-style RedBoot with the old PCI window area set up.
|
| 45 |
|
|
(hal_arm_mem_real_region_top): Better comments, and a safety
|
| 46 |
|
|
check; do not repeat the test for boundary movement.
|
| 47 |
|
|
|
| 48 |
|
|
* include/pkgconf/mlt_arm_sa11x0_nano_ram.ldi:
|
| 49 |
|
|
* include/pkgconf/mlt_arm_sa11x0_nano_ram.h:

|
| 53 |
|
|
* include/pkgconf/mlt_arm_sa11x0_nano_post.mlt:
|
| 54 |
|
|
Add "fixed" region to contain PCI window at 0xfa00000 (250Mb),
|
| 55 |
|
|
well away from normal memory. Adjust ram region size to 15Mb - a
|
| 56 |
|
|
smaller possible memory installation, with the 1Mb default PCI
|
| 57 |
|
|
window removed.

|
| 60 |
|
|
|
| 61 |
|
|
* cdl/hal_arm_sa11x0_nano.cdl: Remove redundant -Wl,-N from link flags
|
| 62 |
|
|
|
| 63 |
|
|
2001-04-12 Hugo Tyson
|
| 64 |
|
|
|
| 65 |
|
|
* src/nano_misc.c (hal_arm_mem_real_region_top): Also report
|
| 66 |
|
|
variants on the CYGMEM_SECTION_heap1 as described by default.
|
| 67 |
|
|
This is ugly, but necessary, else the heap tries to use memory
|
| 68 |
|
|
that is not installed. Oh, for a proper MLT!
|

|
| 70 |
|
|
2001-04-02 Hugo Tyson
|
| 71 |
|
|
|
| 72 |
|
|
* misc/readme.txt: Update the readme to reflect more info about
|
| 73 |
|
|
using the nano target.
|
| 74 |
|
|
|
| 75 |
|
|
2001-03-29 Hugo Tyson
|
| 76 |
|
|
|
| 77 |
|
|
* src/nano_misc.c (hal_mmu_init): Find the real physical address
|
| 78 |
|
|
for mapping the uncacheable, unbufferable PCI window - it might be
|
| 79 |
|
|
various places depending on what SDRAMs are installed.
|
| 80 |
|
|
|
| 81 |
|
|
2001-03-14 Hugo Tyson
|
| 82 |
|
|
|
| 83 |
|
|
* include/nano.h (HAL_PCI_INIT): Disconnect the two ethernet
|
| 84 |
|
|
devices from the PCI bus during init so that we can re-scan during
|
| 85 |
|
|
startup regardless of what happened before - such as
|
| 86 |
|
|
network-enabled RedBoot doing the same setup already.
|
| 87 |
|
|
|
| 88 |
|
|
* misc/redboot_POST.ecm:
|
| 89 |
|
|
* misc/redboot_RAM.ecm:
|
| 90 |
|
|
Enable package CYGPKG_IO_ETH_DRIVERS so that RedBoot is network
|
| 91 |
|
|
capable. Disable CYGPKG_DEVS_ETH_ARM_NANO_ETH1 so that it uses
|
| 92 |
|
|
only the first ether device. Tidy some comments and whitespace.
|
| 93 |
|
|
|
| 94 |
|
|
2001-03-08 Jesper Skov
|
| 95 |
|
|
|
| 96 |
|
|
* cdl/hal_arm_sa11x0_nano.cdl: Removed
|
| 97 |
|
|
CYGINT_HAL_VIRTUAL_VECTOR_SUPPORT_GUARANTEED which is now the
|
| 98 |
|
|
default.
|
| 99 |
|
|
|
| 100 |
|
|
2001-03-01 Hugo Tyson
|
| 101 |
|
|
|
| 102 |
|
|
* include/pkgconf/mlt_arm_sa11x0_nano_post.h:
|
| 103 |
|
|
* include/pkgconf/mlt_arm_sa11x0_nano_post.ldi:
|
| 104 |
|
|
* include/pkgconf/mlt_arm_sa11x0_nano_post.mlt:
|
| 105 |
|
|
* include/pkgconf/mlt_arm_sa11x0_nano_ram.h:
|
| 106 |
|
|
* include/pkgconf/mlt_arm_sa11x0_nano_ram.ldi:
|
| 107 |
|
|
* include/pkgconf/mlt_arm_sa11x0_nano_ram.mlt:
|
| 108 |
|
|
Add MLT definition of PCI window.
|
| 109 |
|
|
I chose 0x1e00000 ie. megabyte 30 because I believe
|
| 110 |
|
|
megabyte 31 is used by RedBoot for buffers or stacks.
|
| 111 |
|
|
|
| 112 |
|
|
* include/nano.h: Take external MLT definition of PCI window for
|
| 113 |
|
|
defining BASE, SIZE symbols. Set the interrupts on GPIO0 and
|
| 114 |
|
|
GPIO1 to be falling-edge in HAL_PCI_INIT(). Don't define any of
|
| 115 |
|
|
this unless CYGPKG_IO_PCI and not assembler.
|
| 116 |
|
|
|
| 117 |
|
|
* src/nano_misc.c (hal_mmu_init): Take external MLT definition of
|
| 118 |
|
|
PCI window. Also define and initialize an int holding the real
|
| 119 |
|
|
address of the PCI window, if CYGPKG_IO_PCI.
|
| 120 |
|
|
|
| 121 |
|
|
2001-02-28 Hugo Tyson
|
| 122 |
|
|
|
| 123 |
|
|
* include/plf_mmap.h (HAL_VIRT_TO_PHYS_ADDRESS): [et al] Use
|
| 124 |
|
|
variant HAL routines which scan the true memory map installed.
|
| 125 |
|
|
This is necessary for dealing with eg. PCI window - also future
|
| 126 |
|
|
similar targets with different physical memory arrangements,
|
| 127 |
|
|
|
| 128 |
|
|
* src/nano_misc.c (plf_hardware_init): Perform MMU initialization
|
| 129 |
|
|
even in RAM startup - so that different configurations of
|
| 130 |
|
|
ROM(RedBoot) and RAM app can work together.
|
| 131 |
|
|
(hal_mmu_init): Perform partial initialization when in RAM startup
|
| 132 |
|
|
- so that ROM settings can be overridden eg. for PCI non-cacheable
|
| 133 |
|
|
memory windows and the like. [Incomplete initial version.]
|
| 134 |
|
|
|
| 135 |
|
|
* include/nano.h (HAL_PCI_INIT): Implement this and all its mates,
|
| 136 |
|
|
ie. a PCI device driver for the nanoBridge and *very specifically*
|
| 137 |
|
|
its two attached i82559s only - it's by no means general, because
|
| 138 |
|
|
it's not a proper implementation of a PCI bridge.
|
| 139 |
|
|
|
| 140 |
|
|
2001-02-22 Hugo Tyson
|
| 141 |
|
|
|
| 142 |
|
|
* misc/redboot_POSTecm:
|
| 143 |
|
|
* misc/redboot_RAM.ecm: add configuration of the Flash Image
|
| 144 |
|
|
System initialization in RedBoot.
|
| 145 |
|
|
|
| 146 |
|
|
2001-02-20 Hugo Tyson
|
| 147 |
|
|
|
| 148 |
|
|
* cdl/hal_arm_sa11x0_nano.cdl: New CDL describing serial
|
| 149 |
|
|
ports - CYGHWR_HAL_ARM_SA11X0_UART1,3.
|
| 150 |
|
|
|
| 151 |
|
|
* cdl/hal_arm_sa11x0_nano.cdl: Also changed the default baud rates
|
| 152 |
|
|
to 38400, having realized that the other port works just fine too.
|
| 153 |
|
|
So you can put your serial line on the non-BSE port for normal
|
| 154 |
|
|
work and not be hassled by out-of-time characters over reset.
|
| 155 |
|
|
|
| 156 |
|
|
2001-02-15 Hugo Tyson
|
| 157 |
|
|
|
| 158 |
|
|
* misc/redboot_POST.ecm:
|
| 159 |
|
|
* misc/redboot_RAM.ecm:
|
| 160 |
|
|
Add CYGPKG_IO_FLASH for RedBoot builds now that flash driver
|
| 161 |
|
|
exists. CYGPKG_DEVS_FLASH_NANO + CYGPKG_DEVS_FLASH_STRATA
|
| 162 |
|
|
|
| 163 |
|
|
2001-02-14 Hugo Tyson
|
| 164 |
|
|
|
| 165 |
|
|
* include/hal_platform_setup.h: Clean up debug and cache hacks to
|
| 166 |
|
|
get it limping along. Import proper value (as read from system
|
| 167 |
|
|
regs) to SDRAM controller setup - in case true ROM startup is ever
|
| 168 |
|
|
used.
|
| 169 |
|
|
|
| 170 |
|
|
* src/nano_misc.c (hal_arm_mem_real_region_top): Add. Support
|
| 171 |
|
|
hal_dram_size.
|
| 172 |
|
|
(hal_mmu_init): Add a SDRAM sizer like others we have. Just in
|
| 173 |
|
|
case. Deals with 32Mb sized parts also.
|
| 174 |
|
|
|
| 175 |
|
|
* cdl/hal_arm_sa11x0_nano.cdl: implements
|
| 176 |
|
|
CYGINT_HAL_ARM_MEM_REAL_REGION_TOP
|
| 177 |
|
|
|
| 178 |
|
|
2001-02-14 Hugo Tyson
|
| 179 |
|
|
|
| 180 |
|
|
* hal/arm/sa11x0/nano: New package, based on Assabet
|
| 181 |
|
|
HAL. This is the nanoEngine from Bright Star Engineering; an
|
| 182 |
|
|
SA1110 CPU + 2x i82559 ethernets.
|
